i don't mind the timing at all, but the amounts late kettle are pretty low.
Double jack uses over 4# of hops per beer barrel, totaling of all additions. That works out to over 2oz per gallon.
assuming you dryhop with at least 2oz, you're at a measly 1.2 oz per gallon - I do APAs at that level, its puny for IIPA. You need to hit it harder with late hops (between 15-0) where you won't get much IBU contribution but will get a lot of hop flavor and some aroma, and then dryhop at least 3oz.
