Here's an interesting article that does uses some additional adjustments for the NHLe to account for differences in the performance based on whether players jump directly to the NHL or via the AHL (
Re-approaching the methodology of NHLe).
The use of the so-called "Wilson Method" for adjustment results in the following NHLe estimates...
KHL 0.73
SHL 0.67
Liiga 0.60
Using those factors, NHLe estimates:
Tolvanen 51.3
Vesalainen 37.4 (adjusts to 40.4 if you adjust for lower ice-time for Vesalainen)
Now, if you want to consider a bit more context, Tolvanen's team (Jokerit) scores about 34% more goals per game than Vesalainen's (HPK).
So, individual production (points/game) as a ratio over team goals/game:
Tolvanen 0.289 (i.e. has a point in about 29% of team's goals)
Vesalainen 0.344 (i.e. has a point in about 34% of team's goals)
Overall, considering adjustments to NHLe and context (team scoring and time on ice), the difference in production between Tolvanen and Vesalainen doesn't seem quite so stark as has been portrayed.
