Ah thanks for helping.
I also use intervals.icu.
In 2021 i make it till 4.6 w/kg in the period december 2020 - 1 may 2021.
In 22 weeks: 12069/22 week = 548 TSS/week and 78 daily avg.
In that period i did not do vo2max, so i will try this year again with a shorter (but steeper) base, followed with FTP and Vo2max, to make it till 5 w/kg.
