We found that if you over throttle going towards the course, it takes a while for PP to settle in. Suggest you take care not to over-speed. If you go in hot, the one and three ball times will be slow the the balance will be fast to make the end actual.
Also, make sure you input crew weight and use the correct skier setting, we use featherweight, then select your Alpha numeric ZO selection. Works great for us on a short setup with a 99 SN with a variety of skiers weight and some varied skill levels.
