@MichaelMihalik which approach did you take to get you back up. I just had a similar experience. Started build with a test of 293 and after build 1 (3weeks on and 1 week rest of actually keeping mostly compliant, the most I have ever been) ftp dropped to 276! Felt good going into the test felt rested, maybe even over rested… same PM same caffeine, same music, so weird…
