What's wrong if my kick serve has less kick than my flat serve?

[New Daddy]

I'm starting to get the hang of kick serves.
The problem, though, is that, on average, my well-hit kick serves seem to have less kick than my well-hit flat serves.
I'm judging the size of a kick by (a) the height of the ball after it hits the service box and (b) the number of bounces the ball makes before it hits the back fence.
My really well-hit flat serve can reach almost 6" on it first bounce and can reache the (opponent's) back fence before the ball hits the ground again.
However, my (what I believe to be) well-hit kick serves do not seem to reach as high and bounces at least once more before the ball reaches the back fence.

From these descriptions, am I doing something wrong with my kick serves? Or are well-hit flat serves supposed to have good kicks as well?

You need faster racquet head speed.

6" (inches) is not really high at all. (joking)

Maybe you should use your flat serve as a kicker, and your kicker as a flat?

Ok, for real ... I think it might be that you are getting much more racquet head speed on your flat serve, therefore you are generating more kick (you are not afraid to go all out, since it's ONLY a 1st serve).

You may be too tentative on your kicker, therefore holding back more than you really should. Even though you may be intentionally aiming to brush/spin the kicker more, you still need racqut head speed.

Just practice more proper form, mechanics, and racquet head speed. Use this aggressive kicker as first serves at first, since you wouldn't be as afraid of it going out. As you get better, use it as your main second serve. When you are confident, you should not hesitate as much when using this kicker as a second serve.

Well your kick serve is going to be slower than your flat serve so it's possible that your kick serve will bounce before hitting the wall even though it may kick higher than your first serve.

if the peak of your kick serve is lower than the peak of your flat serve, you aren't hitting a kick serve or your flat serve has a lot of spin on it.

it might have more sidespin than topspin that is the problem with me but it still makes a good serve because it dips in
