Yes Darky all that is good on a plan where you might have 25% winners with an average divi of $4, but it doesn't work where you have (as IS the case here) returns 80% of the time with an average divi of $2, (which means of course that some divies are less than $1, this is because some selections are bracketed)

So even though there is POT of 5%, most staking plans don't work with it.
