Group SR/ROI and Longest Losing Run Calculator SpreadsheetWhen working through a group of portfolios or systems one to collate them all together one should consider what the net effect of having a number of systems running against one bank. This spreadsheet does just that; all you have to do is to fill in the number of runs, wins and profit for each system into the coloured area and the spreadsheet calculated the net result. Moreover, it takes the total number of runs and the total strike rate and calculates how long the longest losing run is expected to be. Whilst this is an eye-opener (for example over 9000 races an 8% SR system could be expected to have its longest losing run of over 100 races!) this is an essential tool for helping to calculate staking for one's one bank.
