Not enough id in stage mode

[jf8429]

I input the following in stage mode

<stage> id: 0 #stage 1-1
<phase> bound: 900
id: 30 hp: 50 id: 30 hp: 50
id: 30 hp: 50 id: 30 hp: 50
id: 30 hp: 50 id: 30 hp: 50
id: 30 hp: 50 id: 30 hp: 50
id: 30 hp: 50 id: 30 hp: 50
id: 30 hp: 50 id: 30 hp: 50
id: 30 hp: 50 id: 30 hp: 50
id: 30 hp: 50 id: 30 hp: 50
id: 30 hp: 50 id: 30 hp: 50
id: 30 hp: 50 id: 30 hp: 50
id: 30 hp: 50 id: 30 hp: 50
<phase_end>
<stage_end>

But it does not work well, it can only output 20 bandits totally
But my expected value is 22
How can i do this without using

1.Ratio
2.Make an object point to release id

I want a way to change exe
to make it have more id

Is it necessary to edit lf2 source code?
What is source code?
