Unlucky for me that both of them did nothing in the 47 minute(every 13sec avg for both), but weird is that I did work for this fast round, that got accepted. Does server just look how many accepted shares there was between 01:47:24 -> 01:48:02 instead of calcing the true accepted for that round?

Edit: I had no shares for this fast round. Rx: N/A +0.00000000
