its 1m per 15 seconds so 250 mins = 1000m
each support is 100m so 25 mins

Subtract from 23:00 to see when you need to release and support if you want to get desired results

Since you cant control whether or not some */nice guy supports your latern your best bet is to take advantage of the 12x supports you can do instantly.

For medium refine release your latern in the last couple mins, and double support the 6 laterns next to yours, that will put you at 1200m~ just before rewards are given out.
