I can save 45 seconds with best switch so waiting too long is not gonna help and i have no idea what time i always arrive at checkpoint. So i should pull out phone when escaping cops and enter yellow marker in front of Franklins house at:00:49??

I dont have save file before the Long Stretch , should i sacrifice tomorrows run few seconds by saving :D:D

You always leave at midnight. You have three stars which takes a minute to lose. A minute in real time is 30 seconds game time. It takes between 5-10 game time to get in the car and lose the cops. So you will arrive (if not seen by the cops) between 35-40 in game time. It would then take between 18-28 second real time of waiting to get to 12:49. If it works, I will test further with earlier times.

Hit yellow marker at 00:49 yeh. Wait in garage or in front, doesn't matter. You can wait a tad longer if you wish.

So it means i will save 15 seconds or so only, i guess its better then nothing. I wil do no reset attempt on first run and will make a save before long stretch.

Yeh something like that. Really depends how early we can do it. It also has the advantage of being a 'saving grace' is you happen to get seen by the cops and it means there is no chance of crashing and losing time on the drive (which doesn't happen often but still).

Didnt worked for me, tested twice. You should make another save and try again, you just got lucky probably. I might make a save file again to try couple more times. I finished the mission like 25-30 minutes past midnight. Pretty long wait.

It couldn't have been luck, I got it half a dozen times. There must be something else that influences it perhaps.
