Currently total hashrate of the TIPS network is ~500MH/s. But because of the difficulty bug, the virtual hashrate is in fact 2550MH/s, so there's a block found every 5.2 mn instead of 1mn.
That we already know.
tips.bettercoin.org is supposed to have ~80MH/s, or ~16% of the network hashrate, leading to an average of 1 block every 31 to 32mn. This is what their stats is showing.
Now look at the nicknames here https://tips.bettercoin.org/index.php?page=statistics&action=pool
A certain Vovan0512 is hashing at ~9.6MH/s.
He's supposed to have 9.6/2550*1440*2500000 = 13.5 millions TIPS per day on average. That's with 0 orphan/stale, so multiply it by 0.85 and you have ~11.5millions per day.
But it's written ~5.5 millions.
So by searching why it's the case, I just searched the payment distribution for each block here : https://tips.bettercoin.org/index.php?page=statistics&action=blocks
And what can you see on multiple blocks ?
A certain anonymous is getting nearly 50% of the payment, while not appearing anywhere. He has 7* more share than Vovan0512, so he must be hasing at ~70 MH/s no ? But isn't the pool's hash at ~80MH/s. Why does he not appear anywhere ?
In the case that "he just leaved", this still does not explain why Vovan0512 is only having half what he should.
Edit: false alarm it seems, it's only a problem with the calculated TIPS/per day shown, there really was a big anonymous user until 3 hours ago
