I can see why you no longer subscribe! This little calculation bot is useful http://greyhorsebot.co.uk/strikerate.asp although more often than not it isn’t the LLR that defeats a bank, but the bad losing run with a long losing run broken up by a winner or two then another long losing run. As a rule I take the longest losing run (calculated) and at least triple it bearing in mind that the average price of the winners can also have a significant impact. A 20 losing run followed by a 1/1 winner followed by another 1/1 winner is in fact a loss of 38 points! Because these selections have an enormous variance in prices the longer priced selections won’t be as common.
