I got to 2.6.
I used to be really good at it, but not at this 'higher level'. As a sprinter I learned how to 'cheat' the starting official. Most starters shoot after 3 'seconds', but those seconds are kind of variable. So it's more a 'time unit' which is variable for each person. In this game the common denominator is 0.2 seconds, so to get to 2 seconds you'll have to count to 10 (for instance).
If you know 'how to count to three' you can do undetectable false starts. Unfortunately, they got mechanical false start detection nowadays, so my talent is pretty much wasted
