The music seems consisten tto me as well until the end, where it becomes totally random it seems. What I do for the end timing is, once nats message fades, when the VCR timer hits the next number i just count that as 1 , and keep going, if the next number hits as soon as it fades, i exit after i count to 18, since if i left at 17 itll be more like a low 16 exit, although i have a hard time nailing good endings if it so happens that the timer switches right after her message fades, since its tough to determine when its a mid-high 17, and a lot of times i end up getting a flat 18 ending instead.
