Teams that attempted to measure the points in good faith were stessed and most of them showed signs of burn out. They regularly worked 60 hours a week.
Teams that gamed the system and understood the impossible task they were assigned always gave the highest points total to a ticket they could or broke it down into smaller achievable tickets that continuously added to their points totals. These teams were filled with happy stress free developers.
In an environment like that playing by the rules is a suckers game.
When I eventually quit, every sr engineer at the company; 7 total, followed me within 4 months.
