| All insulins have a leading spike, a peak, a downward fall, and a tail (that's what I call them.)
The two major keys when figuring out insulin duration are the fall and the tail. Keep in mind, insulin effects everyone differently, but there are the general numbers. Novolog is about 90% used in 3 hours. Then that final 10% or so is the rail that can last an additional 2 hours. Therefore, one may still notice their BG dropping up to 5 hours after the bolus is given. It just won't be a significant drop in most cases.
