Progression Recalculation is an advanced tool that rebuilds your Xert progression from the beginning of your training history. It can fix cases where your Fitness Signature or training loads drifted due to missing history or bad data—but it is not normally required.
⚠️ Important: A progression recalculation cannot be undone and may change your current Fitness Signature, Training Status, and historical metrics. If you’re unsure, we recommend contacting Xert Support before recalculating your progression.
Quick Answers
- Most users do not need this. Xert usually self-corrects as more rides are uploaded.
- Use it when your history is incomplete or corrupted and your progression no longer makes sense.
- If you do run it, enter your best estimate of your starting Fitness Signature and Training Load at the time of your first activity for best results.
- Review all data before recalculating... if the issue is caused by a single bad file, flag/delete that activity first — a complete progression recalculation is often unnecessary.
What a Progression Recalculation Does
When you run a Progression Recalculation, Xert:
- Uses the inputted Fitness Signature and Training Load as the “anchor” for your earliest activity.
- Re-processes your entire activity history in order (“trickle-down”).
- Re-evaluates Breakthroughs and Near-Breakthroughs along the way.
- Rebuilds your training loads, training status, and progression metrics based on the updated history.
Think of it as asking Xert to rebuild your entire progression from the beginning using a known starting point.
When you should consider a Progression Recalculation
Use this tool when the problem is system-wide, not just one ride.
Good reasons to recalculate:
- You imported a large amount of historical data (or corrected major gaps) and your progression looks inconsistent.
- You had weeks/months of missing rides, then later imported them, and your signature/training loads now feel “off.”
- Your account has multiple corrupted activities (power spikes/dropouts) that caused a chain reaction of unrealistic changes.
- You switched setups and now have a long history of mismatched sources (e.g., wrong sport profile, running power in cycling history) that materially skewed results.
Before you run it:
Try the simpler fixes first:
- flag/delete the obviously bad activity,
- add a couple of real maximal efforts to re-anchor the model,
- or contact support.

When you should not run a Progression Recalculation
Most “normal” concerns do not require recalculating.
Cases where you don’t need it:
- Your signature changed slightly after a hard ride (normal).
- You don’t have many recent maximal efforts yet (do a few hard efforts instead).
- You suspect one activity has bad data (flag/delete that activity first).
- You’re simply new and your model is still settling in the first week.

Before You Recalculate
Do these first to avoid unnecessary rebuilds:
- Check for obvious data errors — Look for activities with impossible max power spikes or dropouts and flag/delete them. Xert Support can help you find & correct these.
- Confirm your activity history is complete — If you plan to import more history (e.g., additional Strava years), do that first—then recalculate once.
- Make sure your sport profiles are correct — For example, keep running power runs out of cycling history if that’s skewing your signature.

How to run a Progression Recalculation
Step 1 — Choose your starting anchor values
For best results, enter your estimated Fitness Signature and Training Load for the time of your first activity in your history.
Why this matters: the recalculation uses this as your baseline and rebuilds everything forward from there.
What to enter:
- Fitness Signature: TP / HIE / PP estimate from that time period
- Training Load: a realistic training load for that time (not your current TL)
If you’re unsure, use reasonable estimates—perfection isn’t required, but wildly wrong anchors can distort the rebuild.

Step 2 — Run the Recalculation
Start the recalculation process. Xert will re-process your history in order and rebuild progression. Depending on the number of activities you have, this can take several minutes, or longer if you have hundreds of activities to reprocess.

Step 3 — Verify the Result
After it finishes, check:
- Your current Fitness Signature
- Your Training Status
- Your XPMC trends (does TP generally rise when training load rises?)
- Recent activities for Breakthrough behavior that matches your efforts

Common Questions (FAQ)
“Will this delete my activities?”
No—your activity history remains, but Xert reinterprets it and recomputes progression metrics.
“Can I undo a recalculation?”
No. Progression recalculation is not reversible. If you’re unsure, contact support first.
“Why did my current signature change?”
Because the rebuild may detect different breakthrough patterns once your history is reprocessed with a new baseline anchor.
“Should I contact support?”
If you’re considering recalculating and aren’t sure why your data looks wrong—yes. It’s often faster for support to identify the root cause (bad file, missing history, wrong source) than to run a full rebuild.
Still stuck?
If you think you need a recalculation, send support:
- the date range of your history,
- what changed recently (imported history, bad files, device change),
- and what looks wrong (TP jump, frequent breakthroughs, etc.).
We can tell you whether recalculation is appropriate and what anchor values to use.
