I'm not sure how you've been making your change since you haven't stated, but you should only have to change the AA effect for rank id's 418 through 422.
Code:
mysql> SELECT * FROM `aa_rank_effects` WHERE rank_id IN (418, 419, 420, 421, 422);
+---------+------+-----------+-------+-------+
| rank_id | slot | effect_id | base1 | base2 |
+---------+------+-----------+-------+-------+
| 418 | 1 | 262 | 5 | 0 |
| 418 | 2 | 262 | 5 | 1 |
| 418 | 3 | 262 | 5 | 2 |
| 418 | 4 | 262 | 5 | 3 |
| 418 | 5 | 262 | 5 | 4 |
| 418 | 6 | 262 | 5 | 5 |
| 418 | 7 | 262 | 5 | 6 |
| 419 | 1 | 262 | 10 | 0 |
| 419 | 2 | 262 | 10 | 1 |
| 419 | 3 | 262 | 10 | 2 |
| 419 | 4 | 262 | 10 | 3 |
| 419 | 5 | 262 | 10 | 4 |
| 419 | 6 | 262 | 10 | 5 |
| 419 | 7 | 262 | 10 | 6 |
| 420 | 1 | 262 | 15 | 0 |
| 420 | 2 | 262 | 15 | 1 |
| 420 | 3 | 262 | 15 | 2 |
| 420 | 4 | 262 | 15 | 3 |
| 420 | 5 | 262 | 15 | 4 |
| 420 | 6 | 262 | 15 | 5 |
| 420 | 7 | 262 | 15 | 6 |
| 421 | 1 | 262 | 20 | 0 |
| 421 | 2 | 262 | 20 | 1 |
| 421 | 3 | 262 | 20 | 2 |
| 421 | 4 | 262 | 20 | 3 |
| 421 | 5 | 262 | 20 | 4 |
| 421 | 6 | 262 | 20 | 5 |
| 421 | 7 | 262 | 20 | 6 |
| 422 | 1 | 262 | 25 | 0 |
| 422 | 2 | 262 | 25 | 1 |
| 422 | 3 | 262 | 25 | 2 |
| 422 | 4 | 262 | 25 | 3 |
| 422 | 5 | 262 | 25 | 4 |
| 422 | 6 | 262 | 25 | 5 |
| 422 | 7 | 262 | 25 | 6 |
+---------+------+-----------+-------+-------+
Change the base1 effect from 5/10/15/etc to whatever you want. 200 points per level being 200/400/600/etc. Make sure you change it for all 7 stats.
I haven't tested this, but it should work fine.
