When it starts to download the next Chapter, can I press the pause on the timer?

Hello, I want to try to speedrun this awesome game, and I have some questions. Is IGT required? Because you can see your total time in the end of chapter 15. And all records - it's not IGT time, It's time in the end of chapter 15. I finish AKUMU in 8+ hours and 110+ deaths, but I loaded checkpoints afrer every death, and I have only 5+ hours and 0 deaths (actually, serious, you can see screenshot in my steam profile) So, If I run this game with 4-5 hours, but If i will load every time after every death, it will only 3+ hours in chapter 15. If I will do that, can It be verified? Thank you. And sorry for my bad english.
