A light bike doesn't replace good fitness.

I posted links to I think 3 studies testing the linkage of FTP to lactate threshold, which all came to the same conclusion - it was nowhere close.
Interesting. The whole premise of WKO4/5, the metrics they track (mFTP, TTE, Stamina, FRC etc.) are based on the premise that FTP is a functional equivalent of MLSS. Tim Cusick does a good webinar on the reasoning behind this, and there are articles too. He talks about LT1, LT2, etc. This premise seems to be backed up by Andy Coggan who, you know, kinda invented the whole power thing and developed those new TTE and Stamina metrics.

I'm not saying I'm disagreeing with you. I'm saying some of the best sports physioligists alive are disagreeing with you.

Just so we're on the same page, you do know what MLSS is right? It's essentially the same thing as FTP, and FTP is more or less a system that allows you to approximate MLSS by doing a time trial alone without the use of "lab equipment."

FTP is closely (but not perfectly) correlated with MLSS. But MLSS itself is an interesting concept and it's really not what most people refer to when we are talking about lactate threshold (i.e., the actual point in which your body begins rapidly accumulating lactic acid, i.e., a threshold of 4.0 mmol/l, or what is commonly referred to as OBLA).

Some people I think play loose with the definition of lactate threshold to include MLSS, when that's really not what we are talking about.

I agree with you. The people using those loose definitions aren't exactly idiots. They are the pioneers and leaders in training with power on a bicycle. Those people looked at the numbers and decided the differences between LT1, LT2 and OBLA were minimal enough and close enough to MLSS that they rolled it all up and coined the term "FTP" - the F, Functional, being the keyword.
