After some discussion in another thread, I decided I’d put some time aside to have fun farming the train. For the sake of clarity and transparency, here are the specifics, so far:
average time (determined using iphone timer): 4 minutes
best time: 3:31, worst time: 4:19
Those times were very easy to meet. In fact, I kept an Infinity in slot 1 and shot every snow pile on the way, without fail, no exceptions. That was a self check to make sure that I wasn’t pushing too hard.
average time at which I engaged the snowman: 1 min, 48 seconds
time to kill averaged less than 40 seconds
I didn’t rush train checks.
