Like to track my ROI's by blocks of 100

[Vetstadium]

Here are 500 ROI's and just started over 500 with a horrible 2 for 18 placement(yuck) so this next 100 gonna be low. 1) .368 2) .209 3) .074 4) .157 5) .173 So yes I can see there is a big swing in ROI's and quite possible to go 100 with a negative ROI I am off to a very bad start with my first 40 or so over 500 but a nice string of firsts can fix that. These are at 20's and 30's SNG's.
