Waru for releasing monsters?

This is what I'm getting:

Level	Waru
3	0
4	16
5	40
9	216
10	580
11	652
12	732
13	820
14	916
15	1020
20	2560
21	2712
23	3040
24	3216
25	3400

The table seems to be right for the most part, but there seems to be jumps at level 10, and probably 20, there will probably be a final jump at 30 as well, but I have yet to encounter one of those. I can upload screenshots in a little bit.

Also, it makes me sad to say that I experience almost no lag in the Korean version vs our own Monster Life. I assume we just have more people playing Monster Life right now than they do,"now" as in the time that has elapsed since it was released, a few days for us vs a few months for them, and this time of day, 7PM here, 4PM server time, vs 8AM in Korea.

A quick glimpse of that makes me think that for levels 10 to before the next jump (probably 19), they simply add 300 to the value calculated; then from 20 and onwards (probably to 29) they add 1200 to the value.
As for the lag, I get a lot of lag no matter what time of day it is
