The interesting thing to note here is the validation that the top goal scorers don't just get their numbers due to taking lots of shots, but that they do appear to score more often when they do shoot. Guys like Jaromir Jagr, Ilya Kovalchuk and Alexander Ovechkin (who ranked 3rd, 5th, and 6th last year in total ice time for forwards) also rank highly in slap shot scroring, at #3, #11, and #12 respectively.
For this study, I screened for the top 100 players from last season in terms of slap shots taken, broke down the results based on range, and summarized to obtain individual scoring percentages as shown in the picture below. Empty Net goals are not included in these figures, and I've highlighted some of the more interesting cells where percentages are high (green) and where they are abnormally low (red).
