verters pool is configured bad, or missed the codefix for lyra2rev2. i dont know (i have just tips)
Here is the explain: i searched a block with (almost) same difficulty (397-399):
This is from your pool (398.5 diff -> 102022 expected shares):
This is from verters pool (398.21 diff -> 50971 expected shares):
Yes this is wrong calculated.
this is the last hour stats from verters pool (397.74 diff -> 101824 expected shares):
If you compare the diff here with your pool, this expected shares looks good.
So, bad news for you: "Block Overview" stats is good on verters, "Last 20 Blocks Found" stats is bad.
and bigger bad news for you, that last block stats bad for "wrong side":
398 diff required ~102k excepted shares, the block has 144k shared, so the block luck is 141%, not 283%.
I help you to understand this: they show worse block lucky, than the really block lucy on pool
