I don't think that's right.
According to TrainingPeaks, who I think invented the TSS (or at least the current variation in question),
"While individuals will tend to differ in how much training they can tolerate, depending on their training background, natural abilities, etc., the following scale can be used as an approximate guide:
TSS less than 150 - low (recovery generally complete by following day)
150-300 - medium (some residual fatigue may be present the next day, but gone by 2nd day)
300-450 - high (some residual fatigue may be present even after 2 days)
Greater than 450 - very high (residual fatigue lasting several days likely)"
You are saying TSS that is greater than 100 is impossible because 1 hour sustained effort on FTP is IF of 1 and TSS of 100.
