I set my block up as a relay and it seems its caught up now, seems like its ahead of [pooltool.io](http://pooltool.io) stats. is it okay to generate kes number if the slot number is ahead: [pooltool.io](http://pooltool.io) = Slot:293144 (67%) Slot : 293183 67.9% ---

> [@godofrefuse](#): > > [pooltool.io](http://pooltool.io) = Slot:293144 (67%) Check the block instead of the Slot. This should show the same number. Think the slot number on pooltool just is a little behind time → Generally I think you cannot be ahead of time. So everything should be fine ---
