On the 'status table' on your page I can see 'Expected time to block (pool):' which is in seconds. Is this perhaps what you refer to as the time for the pool to find new block? Can you help to update the information on 'Recent Blocks' at the bottom of the page http://p2pool.e-pool.net:5950/static/
"Expected time to block" for BTC, BCH or any coins for High Diff is not working correctly anymore as is hard to calculate correctly
I found the block stats including "Expected time to block" and other activities here: http://p2pool.org/stats/ I would suggest linking up the BTC e-pool stat if possible. I found many important and helpful clarifications here: http://p2pool.org/learn/
Thanks for the e-pool.
