Saved Calculations

What Are Saved Calculations?

Saved Calculations is a central library for calculator results you want to revisit. Instead of taking screenshots, copying numbers into notes, or recalculating the same inputs every week, a compatible calculator can store a structured snapshot and this page can display it later.

The feature is most useful for repeated assessments. For example, an athlete might save an FFMI result at the start and end of a training block, keep several muscle-gain projections under different assumptions, or store training-volume calculations for multiple mesocycles. Each record can carry enough context to make the number meaningful when you return to it.

Why Save Fitness Calculator Results?

Most fitness calculators are useful at a single moment, but their value increases when you can compare multiple moments. A single FFMI result may tell you where you are today. A sequence of FFMI records can show whether estimated lean mass has changed across months. A single training-volume calculation can help plan one week. Saved training-volume snapshots can show how your programming evolved as recovery and performance changed.

Progress comparisons become easier

When records have dates and consistent metrics, you can compare them directly. That is more reliable than trying to remember whether a previous result was 21.8 or 22.1, or whether your earlier projection assumed a six-month or twelve-month timeframe.

Different scenarios can coexist

Projection tools often involve assumptions. Instead of overwriting one scenario, you can save a conservative case, a middle case and an aggressive case under different names. This is particularly useful for muscle-gain projections, calorie planning and programming choices where there is no single guaranteed outcome.

Saved context prevents misleading comparisons

A raw number without context can be deceptive. Notes such as “morning body weight,” “DEXA body-fat estimate,” “end of cut,” or “higher-volume block” can explain why two otherwise similar calculations differ.

How Browser Storage Works

This page uses the browser’s localStorage mechanism for its shared saved-calculation library. The Web Storage API allows a website to keep string-based data associated with its origin in the browser. FFMIPro stores the structured records as JSON and reads them back when you open the dashboard.

You can read more about the underlying technology in the MDN documentation for localStorage. The practical takeaway is that browser-local storage is convenient but not the same as a cloud database.

Storage behavior can vary with browser privacy settings. Private/incognito modes may treat data as temporary, and browser cleanup tools can remove site storage. For that reason, the export feature is not just a convenience—it is the backup path for records you care about.

How to Back Up Saved Calculations

The dashboard provides two export formats because they solve different problems.

JSON export for backup and restore

JSON preserves the complete structured record: title, calculator type, saved date, summary, metrics, notes and source link. Use JSON when your priority is moving the saved library to another browser or restoring it after clearing data.

CSV export for spreadsheet analysis

CSV is easier to inspect in spreadsheet software. Because each calculator can have different metrics, the export stores a compact metric summary alongside the standard record fields. This makes it useful for sorting dates, adding your own columns or building progress logs.

Import carefully

The importer expects a JSON array of compatible saved records. Imported entries are normalized and assigned IDs when necessary. If you import a backup that already contains records from the current browser, duplicates may appear; use the dashboard’s delete controls to clean them up.

Using Saved Calculations for Progress Tracking

Saved records are most informative when the inputs are collected consistently. If you compare FFMI over time, try to keep body-weight conditions and body-fat estimation method reasonably consistent. If you compare training-volume plans, label the phase and use the same definition of a hard set. If you compare nutrition projections, note whether the goal, calorie surplus or training status changed.

Example: FFMI history

You might save “January baseline,” “April check-in” and “August check-in.” A useful record would include FFMI, normalized FFMI, estimated lean mass, body weight and body-fat percentage. The notes field could record the measurement method or phase of training.

Example: muscle-gain projection scenarios

Instead of treating a projection as a promise, save multiple scenarios. One record might represent conservative training quality and another might represent excellent adherence. Months later you can compare actual measurements with the original assumptions.

Example: training-volume planning

A coach or lifter can save a base-volume week, a specialization block and a deload template. The calculator type filter then turns the general saved library into a quick collection of programming snapshots.

Privacy, Data Retention and Limitations

A local-first dashboard avoids requiring a user account for basic saving. That can be desirable for simple utility data, but the tradeoff is that persistence depends on the browser environment.

• Clearing site data: can remove the saved library.
• Changing browser: does not automatically move the records.
• Changing device: requires export/import for manual migration.
• Private browsing: may discard data after the private session ends.
• Browser storage limits: local storage is finite, though simple text calculation records are normally small.
• No medical record function: this utility is not intended to act as a clinical health record system.

Do not store highly sensitive personal or medical information in free-text notes. Keep notes limited to the context required to understand your fitness calculation.

How FFMIPro Calculators Can Integrate With Saved Calculations

The page exposes a small browser helper under window.FFMIProSavedCalculations. A compatible calculator can call the save() method after it calculates a result. The record can include any number of metrics as a simple object.

This shared format means an FFMI calculator, muscle-gain projection tool, training-volume calculator and nutrition planner can all feed the same dashboard without needing identical outputs. The manager focuses on common metadata while displaying each calculator’s own metric pairs.

For implementation quality, the calculator should only save after a user explicitly chooses to save a result. Avoid silently creating a new record every time an input changes, because that can flood the saved library with accidental duplicates.

Best Practices for a Useful Calculation History

1. Use descriptive titles. “August FFMI Check” is more useful than “Result 3.”
2. Keep the measurement method consistent. Historical comparisons are easier to interpret when the underlying inputs were gathered similarly.
3. Add short context notes. Training phase, goal or measurement condition can be enough.
4. Do not over-save. Save meaningful checkpoints, not every minor input experiment.
5. Export before clearing browser data. JSON is the preferred restore format.
6. Use CSV when analyzing trends. Spreadsheets are better for custom charts and long-term tabular comparisons.
7. Remember calculator uncertainty. A precise-looking saved number can still depend on imperfect body-fat estimates, assumptions or formulas.

Saved Calculations works best as an organizational layer around FFMIPro tools—not as evidence that a projection or estimate is exact. Use the records to preserve your assumptions and observe trends while keeping the limitations of each underlying calculator in mind.
