Tapster X Y position not working properly

[formiganinja]

Hi, I need you guys to check if the tapster coordinates algorithm is correct, because I am trying to tap a coordinate on screen after calibrate using the RobotCalibration app, but the position is always wrong. I noticed that the algorithm used here and the one from tapster official github is a little different and this branch hasn't been updated for one year. My goal is to get the coordinates using browser.elementByName().getLocation() and pass to robot.tap() method without calc the position by myself.
