50x on one map is a lot. Pretty sure I've only run there once and it was with you.
And I'm not even counting that one!
Ah, so I have run 0 times on Pawtuckaway using the jjcote accounting system. Shame.
Interesting. I have no such statistical capability, but just relying on memory, Blue Hills and Pawtuckaway would certainly be candidates, Sebago and Surebridge, Mt Tom, Norwottuck, Huntington, Paugusset, Gay City, Osbornedale. As many times as I have been to Sessions, at least half of them have been as a course setter.
I like the Mike's Maze is so far up the list, despite being a relative newcomer!
Even without checking any records, it's clear that Pawtuckaway will win easily for me (with Ratlum second). If I include the five or six vampire-o's, I should be around 40. (And with the canoe-o's ... but I guess that counts as a different map.)
My 50 includes the canoe-Os -- it's really just a slightly extended version of the regular map.
