I'm struggling with the same problem. Couple good lights, then some way late & some red. I'm sure lack of seat time is not helping.
I just bought the ProTree Pocket Pal practice tree to see if it's me or the car. So far, it looks like I'm the problem. I have it set-up as a .5 second full tree, roll-out at .290, delay box set at 1.040. I can get a string of .00x & .01x lights & then a .04x or .05x on the practice tree. Couple things that seems to make a difference on the practice tree is to make sure the hand that holds the button is braced against something solid. And the button press & release movement is inline with the button,
Good luck & let me know if you find the secret.
