The other 3 pieces of advise for these segments are:
(1) Run in a circular fashion from window to window. If there are no dinos at the next window, move on to the next one quickly using the sprint.
(2) Increase the aim sensitivity to about 6 or 7. The game starts you off at 3 and it feels like moving through molasses.
(3) Use the adrenaline rush to slow things down to minimize damage to the windows and kill the dinos quickly.
