Option to change custom Heart Rate Zones for activities in a specific period // Option to change FTP only for new activities
In my settings my Heart Rate Zones were (automatically) based on Max Heart Rate. Then, until a year ago, I changed them to my custom Heart Rate Zones, mainly because the Zone "Z4 Threshold" was a bit to high. So all in all only little changes.
But this change in the settings from automatic to custom had a huge impact to the calculation of the relative effort for new activities – the relative effort is now much lower for new activites. In the following year, my fitness curve dropped massively, although I trained lot more.
So, there has to be an option to change the custom Heart Rate Zones for all activities or only for activities in a specific period, and then recalculate the relative effort for these activities, and generate a new Fitness & Freshness curve. Otherwise the Fitness & Freshness curve is useless!
The funny thing is, when I change in my settings my FTP – because I've made a FTP-Test and I've improved my FTP – this value affects to all activities, also to the activities in the past. Also useless, because my FTP from today has noting to do with my FTP from two years ago ...
So, there also has to be an option to change the FTP only for all new activities, not for activites in the past!
