Threshold Power on Progression Chart

I can only see my threshold power on the progression chart until around mid-Aug. Since then I undertook some build training and now switched back to base training. Should the threshold power line until now, or is it normal for it to only show until mid-August? Thanks.

On the progression chart, it will show until your last activity where you had a breakthrough or the activity where you had efforts that were close to your current fitness signature. I would suggest that you include maximal efforts in your training (only need a few minutes) every so often to keep your fitness signature up-to-date (this is like a coach asking you to do a 20 minute FTP test every so often). We’re working on a better algorithm to track your fitness number during periods without maximal effort data. This should become available over the coming months.
