(Firstly, sorry if posting in the wrong place....)

Just quickly after clarification on a rule that's been bugging me for ages (and something I don't see often enough to remember, and so clarify) - coincidental minors... there are times when it results in a change in the on-ice numbers, and others when it doesn't change anything.

NHL.com's rule page makes it about as clear as mud water, and from what I can understand, it results in a reduction of on-ice numbers unless there are one or more penalties still on the clock?

So..... is that:
a) Right?
b) Include misconduct / fighting penalties that do not affect the team?

Not only have I worried for ages, but I'm trying to parse NHL.com's play-by-play data for my own statistical analysis, but the reports aren't quite right so I'm having to calculate the PP times manually :(
