stick car 4 speed best shift points

If you have a Racepak, just make a few runs at different shift points to get some data, then you can change the individual "0" set points on the runs to visually compare the different shift points. By changing the "0" set points, i'm talking about syncing the runs to a much later point other than 1st movement of the car. I like to pick a common driveshaft rpm that occurs after any tire spin but before the lowest shift point, like maybe set them to "0" at 2000 driveshaft rpm to compare all the 1/2 shifts. After you overlay the runs, you can expand the graph with the "+" button to make it easier to see which shift point added driveshaft rpm at a faster rate. When you are done comparing 1/2 shifts, change the "0" points to a common driveshaft rpm that occurs before the 2/3 shifts and compare those.
