No.
His shooting percentage will come back to earth. He can easily shoot a career high (15-18% isn't out of the question versus his previous high water mark of 8.8%), but he is not going to finish the year shooting 22.7%.
And then his on-ice shooting percentage is 19.5% at five-on-five (this is a measure of how all Caps players are shooting while he is on ice). For context, McDavid's career number is 12.9%.
The great news is that he's on pace for roughly 30 goals and 75 points. He could slow down and still finish with 20+ goals and 60 points which would be an outstanding year for a player who has never cracked 30 points or 10 goals in a single year.
On a semi-related note, McMichael's OiSH% is a far more reasonable 14.3% at 5 on 5. The goal-scoring will slow down, but the points production is sustainable based on that measure (which I have found to have a ton of predictive power for guys who get off to hot starts and eventually slow down).
