So, specifically, MJ, DavidSauls, Big Sky, and all the others: do you really believe the stroke penalty matches Schusterick's scorekeeping mistake? Come on.
Yes.
I once suffered this penalty---once is enough to make me diligent forevermore---and have administered it as TD, and it has always seemed appropriate to me.
The timing of his error magnifies it, but it's still the same rules violation, and should have the same penalty.
