A question, these are the remaining N-Factors dates:

11 5242880-8388607 36.4 02 / 28 / 14 @ 04:21:20pm UTC 1MB
12 8388608-12582911 49 04 / 06 / 14 @ 02:10:08am UTC 2MB
13 12582912-16777215 48 05 / 24 / 14 @ 03:15:12pm UTC 4MB
14 16777216-33554431 194 07 / 12 / 14 @ 04:20:16am UTC 8MB
15 33554432-41943039 97 01 / 22 / 15 @ 08:40:32am UTC 16MB

My 290 gets around 350 KH/s now and that will be 175 at some point tomorrow after the next change. By the last change my 290 will only be getting ~11 KH/s. I know you still mine the same number of coins but is that still the case even on the last one? Or will the point of stopping mining UTC actually come before that?
