Ask @MidasCoin:

I have always read that pool mining and solo mining will yield about the same payout over the long run. In the few days of mining I found 9 blocks, 450 Midascoins, yet my earnings, confirmed and unconfirmed show to be less than 5 Midascoins. Seems I would be much better off solo mining, agreed?

Finding a block on the PoM distribution system is mostly "visual" reporting.
This mean that the system assign the block to the user that submitted the last share on that round, and is not linked to the real block finding that is made through the dedicated generation nodes of the PoM distribution.
What happened basically is that for 6 times you submitted the last share before the block was accounted, so that kind of comparison cannot be made ;)
