Curious to see others try it - Justin, Ryan and I ran into parity on a ridiculous number of skeletons. I think I had five starts thrown out before I got 21 to 4 corners with 7 minutes to go.

I did 13 solves in a German forum, I'll consider this PB average of 12 (I did do solves in between, but I didn't care enough to create a "global session" for them):
30, 28, 28, 28, (DNF), 27, 24, 32, 30, 29, 27, (22) = 28.30 Average of 12
The first solve was a 33 so I decided to roll it.

Last three solves are 26.00 Mean of 3. I'll now include each solve I do in a big session, like porkynator. Let's see if I can roll the 30.
Found myself some stickers trying corner3-cycles. And nothing worked.. After like 20 tries. I recognized the problem; one of the stickers was on the wrong side of the corner.. So dumb..

I know that pure 8 move corner commutators are most often used for insertions in FMC. Is it possible that one may run through an entire skeleton without finding a spot where the corners can be cycled with 8 moves? Should A9s and other more complicated commutators be used?

I know that Jay has had skeletons with no 8 movers before, but they're extremely rare. In a 60 minute time window, I don't think it's usually worth the time looking for insertions longer than 8 moves. If your skeleton is that bad for insertions and you have the time, you're probably better served looking for an alternate finish.
It's totally possible, it can propably even happen that 10 moves is optimal for a single insertion. On the other hand, I've seen cases where 9-movers somehow resulted in better insertions than 8-movers.
This can be especially crazy when you have two insertions. Sometimes the optimal insertion requires some weird 9-mover as your first insertion, and then the second one cancels a lot.
At German Open we had a funny example of the "unfairness" of insertions:
1. Jan 27 (23 for L3C)
2. me 28 (22 for L3C)
3. Sébastien 30 (21 for L3C!)
Thanks to guys for letting me know FMC mean of 3 competitions in other times,
like Cross-strait FMC 2014, Guangdong Open 2014, Master Challenge 2014,
although I could not make it.

Many promising starts were found. For example,
2x2x2 block: L D' R2 F'
2x2x3 block: L' F' D2 F L' D'
F2L minus 1 slot: L B L B2
looks great, but I couldn't finish it nicely.
On inverse,

[2] L U2 R' B'
[3] B2 F R2 D
also look interesting, but I couldn't find any good continuation.
So dumb..
