The last 200m are different since 1993. That's why this common section ends at the crossroads where the 2 routes differ.

Details on performance thresholds
The threshold depends on several information : the stage and last climb duration (no threshold if effort < 20 min), its difficulty, etc.
Here is the method used on this website:
Mountain stages > 4 hours:
> 450 W (78kg-standard) : MUTANT
> 430 W : MIRACULOUS
> 410 W : SUSPICIOUS
< 410 W : HUMAN
Single-col stages > 4 hours or time-trials:
> 465 W (78kg-standard) : MUTANT
> 445 W : MIRACULOUS
> 425 W : SUSPICIOUS
< 425 W : HUMAN
