Maybe only a jump of a couple hundred rpm (max) on my car.
I just shrug it off. Not the right answer, I know.
Something similar was happening on my Explorer. Turned out the torque converter needed to be replaced (at only 57k miles!). Obviously that's irrelevent here, except that I was also tempted there to just ignore the rythmic rpm blips at steady 35-45mph speed (only about a 50 rpm bump, hardly noticeable). Glad I didn't - the torque converted could've exploded and I would've had much bigger problems....
