Hash rate just quadrupled?
Edit: Briefly.
that is me renting gear. I do it here and there. I am near the top of the list in stats. I keep 2-5 th steady and when I feel lucky smack the pool with 100th for an hour or so.
the upside if you do this and make 2 fast blocks you really score on the second block. the down side is most likely it won't happen. then you did not score at all.
It is kind of like solo mining with a twist. if I rent for 1 hour's time and the second block comes fast I get half the coins. but getting 2 blocks in an hour is unlikely. even getting one is not that likely.
If I get no blocks during my high hash time my btc due goes up just a little bit. say 1.1 turns to 1.2 then I need higher hash in my low time to maintain that hash and not let it slip.
right now I am at 1.54912 btc and on top of the list .. my hash is at 5.9th I will move some off the pool and drop to about 2.9th I will do this for about 6 hours you will see my 1.54912 btc drop over nite down to maybe 1.52 btc
