5:00.00 -3:47:08 = 1:12.92
1:12.92 + .75 (1 guard cinema)= 1:13.67 run, give or take .01+
1-guard cinema add .75
2-guard cinema add .85
I've testesd this many time, its the difference in cinemas is .1, give or take a .01.(thats far too hard to find out.)
So wouter could have gotten 1:13 with a 3:46.75 or 3:46.76 to be safe, based on the cinema he had.
