Is it possible to use RPE as a LOAD estimator for sports such as Alpine Ski ? I normally manually add based upon RPE/HR Zone per hour using Joe Friels estimator.

Thats a good idea, presumably only if HR is not available? I have added this to the todo list.
I wish we could alpine ski this year… 
HR is available but it didnt estimate in this case ?
Luckily here in Swissland we can still for the moment.
