Changes made for Pathfinder 5226 controllers.

For background on the overshoot parameter logic refer to:

SCN 4619 - 5226; Added Backgauge Overshoot Distance Logic

All of the overshoot logic on the 5226 was tested on a machine configuration that had no spring finger on the machine. When there is a finger the 5226 will adjust targets for the backgauge and visual feedback to account for when the finger is active. A bug was found with the overshoot distance on a machine that has a spring finger in which after the first move the backgauge will no longer overshoot when the finger is active.

The bug ended up being a calculation for the backgauge target for the overshoot move to ignore the fact that there is a finger active. The solution was to make sure that the finger offset distance is taken into account when deciding if the backgauge needs to overshoot.
