I you look on the pool page, you have a large number of shares on the 26 and a lot less the days after:
26: 1026688
Following days: 228132 192199 162442 85495 total:1694956
So it looks like the 26 is the sum of what you had mined previously.
and he can check totals against ck pool since he is 100% this run that total of 1694956 should be a little under ck's

a quick comparison shows ck at 1697140 just a bit higher then 1694956
all info comes from ck links like the one above.
zOU and cryptoglance organize it. Since ck never resets numbers on the shares. by combing stats we can keep track.
I also feed in a lot of extra free hash. this helps the part A prize levels at my expense. It it pretty much a push for part B prizes.
but you the miner have option to go low as 1 stick or as high as you want.
I do like the idea of letting part b shares stay alive the entire 30 day run. This is very unusual in the world of btc
