FTP Detection Way Out - What Did I Do Wrong?

Hi Guys,

I think I may have broken the system…

Quick history:

FTP usually around 275-280.

I got ill.

Month ish off.

TR Ramp Test - 253 watts. I get this this is fine.

I stick to my program and get some good progression levels.

3 weeks later - FTP detection says it should now be 239 watts.

Day later, I PB at a time trial with NP of 278 watts which would give me an FTP of around 265 watts.

Now either I broke the system, or I did something wrong.

Would be good to try and workout why my predicted is so low.

Thanks,

Pat.
