Tuning Hatsan Airtact .25, accurate?

Gentleman over on GTA wrote a pretty through article on how to adjust those triggers to make them better and they are very different from the ones that came on the older Edge/Striker/1000 models: https://michaeljbernard.wordpress.com/2019/03/23/2019_03_23_airtact_trigger_adjustment/ 

Random lame opinion is buy one, shoot the bejesus out of it for 3 weeks or so, then decide if you want to keep or not as you'll still have time in the 30 day return window to send it back..well, depending where you buy it from anyway.
