**What’s new**

Premium riders on the web can get **two complementary ways to read the same eFTP suggestion**. The familiar **power-curve** path still comes from your **strongest 8 minute–1 hour** power effort in the recent window. The new **HR extrapolation** path adds a second watt estimate derived from how **power and heart rate** line up in your riding, projected toward your **lactate threshold heart rate (LTHR)**—using the threshold BPM from your profile, or an LTHR **estimated from max HR** when you have not set threshold HR yourself.

When both numbers are usable, the **Estimated FTP** suggestion modal shows them as **two tappable cards** (Power curve vs HR extrapolation). The summary line, suggested watts, and change vs your **current eFTP** all follow **whichever card you select** ; Tempo initially selects the estimate that **differs more** from your current eFTP so the first screen matches the stronger signal. You confirm with **one Accept** for the selected lens, or dismiss without changing. For very large suggested drops, the modal still surfaces a **sanity-check** reminder before you commit.

**Why it helps**

You can weigh **measured benchmark power** against **how your cardiovascular system responded** in the same period—useful when trainer or pacing quirks make one signal more trustworthy than the other, without bouncing between tools or spreadsheets.

**How to try it**

On the web, open **Settings** → **Profile** → **Training** (the tab with FTP and heart-rate fields). When Tempo has a suggestion, the **Estimated FTP** modal opens from the performance area on that tab; if you closed it, use **re-estimate** when you are ready to revisit it. Tap **Power curve** or **HR extrapolation** to compare, then **Accept** for the lens you want—or dismiss if you are not ready.

**Note:** eFTP calculation and this suggestion flow require a **Premium** subscription.
