Just because you found a block in a pool doesnt mean you would of found it solo mining.
Heres a example
in a pool youd have like a 1 in 7,000 change of finding a block. On your own it would be more like 1 in 700,000
most random thought i've ever seen. no, it's not 1:7000. no, it's not 1:700000. case1 is not even supposed to be any different from case2.
