The block detection is delayed for up to 2 hours. The stats it self isn't delayed, but we made it harder to pool hop with delaying detection/showing of new rounds and blocks.
Exactly the same as BTC Guild, deepbit and other prop-pools does it - to avoid huge amounts of pool hoppers.
How can you say the stats aren't delayed when your site says:
Current round: 14 hours blah blah blah
and then 3 minutes later it says
Current round: 45 minutes blah blah
Previous round 13 hours 15 minutes
It does this ALL the time. You are delaying stats. At least acknowledge it and make it apparent to your users. When your JSON API is giving incorrect "round_shares" for over an hour, that is called delaying stats.
Also, I asked you weeks ago if you were delaying stats and you without hesitation said you were:
Its your pool. Do whatever you want with it. I think it would be nice if you told your users on the stats page that they are possibly looking at lies put in place to try and stop pool hopping.
