Hard to tell, but that looks textbook to me!
In general any delay at Vr and or slightly slow rotation rate on the -800 , and you end up with V2 plus 15 to 25 kts.
In the N-1 case after V1 but before Vr obviously this RWY is tight, and a prompt rotation at Vr and a steady V2 climb is essential.
I was out of there with a full aircraft , over 4 hrs flight and flaps 25 the other day. No margin except for bleeds off next. Worked like a charm!
The Old Lady will perform! Just make sure You do not let her down if Murphy pulls a trick around V1 and the next few seconds,,,,,
Happy Take Offs and Landings
