that's good, especially about ocminer, i've some issue with that pool, earning is not right at all, they are founding block with high %, it mean that you're losing profit if you mine there, up to 30%
What you mean is "variance" - sometimes blocks are found fast, sometimes block are found slow. It evens out after time. In the last hour we've found twice more blocks than calculated, so your earnings are actually almost 200% and you'd have won a lot of coins. Over the last 24h average luck is at 80% so you actually won 20%.... Of course there are also days without this great luck..
The green column is the luck column. Below 100% means more blocks, above 100% less blocks than calculated based on hashrate/shares over time:
Unfortunately even when I release all the source, I cannot fight variance or if you a recipe to be "more lucky" than others
WoW Tank you all for the great work !!
