Good info. My guess is that is either the backend of s1 (POT) or front end of s2 (4:00-4:30). It's interesting to balance this against
@JoRo16's value of 209xx with a very close 1:55 HM (about 75 seconds from the cutoff rD told me). So I think that tells us that these 207xx numbers are probably the front end of s2. Interesting nonetheless.
Correct me if I'm wrong. For Wine and Dine your bib number made it appear you were in a different starting group, but the actual assignment ended up being s2. Is that right? This would seem different in that now your bib number better matches what we believe to be your group assignment despite your registration time otherwise.
Something definitely seems up. So mentally, I'd prepare to have to go to Runner's Relations. With that high of number, the assumption is the POT didn't get accepted and you've been assigned s6.
