So I notice that the rules on the first post don't say anything about non-rolling (even though there was a lot of discussion earlier about it) - does that mean that rolling averages are okay? And if not, how long do you have to wait before starting a new non-rolling average? (That's probably the biggest problem with not allowing rolling averages - it's just so arbitrary to not allow them. It's pretty much a way to make the goal tougher simply by making it more improbable.)
Anyway, here were my first 7 solves today:
DNF, DNF, 1:56.61, 3:00.32, 2:05.08, 2:38.79, 2:04.81
So if we're allowed rolling averages, that gives me a 2:16.23 average. Still nowhere near the goal, but a little better than my previous try.
Oh, and my true average is probably somewhere around 2:15, and I'd guess my average (at home) is around 70%. (It's slightly worse than 50% in competition.

)
And byu, I think it's silly for you to practice memorization at this point - execution is your whole issue. Do you pause a lot during your solves?
I'll just start keeping all my attempts here. Tries 1 and 2 are from above.
Try 1: DNF, 2:46.59, 2:12.20, 2:30.53, DNF =
DNF
Try 2: DNF, DNF, 1:56.61, 3:00.32, 2:05.08 =
DNF
Try 3: 2:44.14, (2:15.42), 3:03.64, 2:20.59, (DNF) =
2:42.79
Try 4: 2:54.11, (3:15.03), 2:39.34, 2:20.86, (1:36.89) =
2:38.10 (I had 9 successes in a row - my best RA was 2:15.53)
Try 5: 2:34.07, DNF, DNF, 2:50.04, 2:22.89 =
DNF (Terrible memory recall problems.)
Try 6: 2:20.79, 2:12.64, 2:10.26, (DNF), (2:04.86) =
2:14.56 (Cool - finally sub-2:15! Consistent, but unfortunately no sub-2's.)
Try 7: 2:03.59, DNF, DNF, 2:36.26, 2:08.95 =
DNF
Try 8: 2:43.32, 2:37.13, (DNF), 2:46.04, (2:23.71) =
2:42.16
Try 9: 1:52.65, 2:10.76, 3:33.34, DNF, DNF =
DNF (It started so good, but then my brain turned to mush and I couldn't remember anything.

)
Try 10: 1:57.25, (2:12.58), 2:08.94, 2:08.94, (1:48.65+) =
2:05.04
Try 11: 2:01.06, (2:45.43), (1:50.65), 2:35.22, 1:52.76 =
2:09.68
Try 12: (DNF), 2:32.47, (3:08.36), 2:36.15, 2:25.70 =
2:31.44 (I hadn't tried this in over a week; I've gotten rusty.)
Try 13: 1:53.92, 2:31.76, 2:36.93, DNF, DNF =
DNF (The fourth one was 1:53.43, just 2 corners twisted. The fifth one was going good too, but then it slipped in my hands.

)
Try 14: (2:03.86), (DNF), 2:06.28, 2:49.72, 3:53.72 =
2:56.57 (Started pretty good, but my memory started failing me toward the end.)
Try 15: 2:45.25, 2:02.90, (DNF), (1:45.93), 1:58.16 =
2:15.44 (This was feeling good at the end - pity there's the "no rolling averages" rule.)
Try 16: (2:36.92), (DNF), 4:59.87, 3:53.87, 3:34.96 =
4:09.57 (My first try with BH corners.)
Try 17: (2:05.43), 2:30.35, (DNF), 3:19.29, 3:15.81 =
3:01.82 (First 2 with 3OP corners, last 3 with BH.)
