1) Maybe. Maybe more, or a lot more, or maybe nothing. 10.1 doesn't guarantee penalties.
2) Yes, although the phrasing of the question masks the subtly that the verbiage of the rule also handles general delays of the entire field, which would then lead to the possibility that one could start at a time which was NOT their officially published time but receive no penalties in that scenario.
3) Cannot be answered conclusively, as both the questions and the answers have multiple conditional statements in them. Clear as mud?
The good news is we'll have a "timing class" on the schedule, on Friday I think. We can all sit around the pool (or somewhere) and talk about it. :)
Actually, I'm going to revise 2, because it's incomplete, so not "yes", but "no". You get 10 for out of sequence, and then you get the minutes you're late by. (10.4.1.2 AND 10.4.1.4)
