I haven't seen anyone post a
CronusMax script for ring boosting yet. So, with a 10-year delay, here is my script.
Have 4-5 people in the ring. Place a dummy from the other team just outside the ring and
press 
once. This will start the script on a loop and make him run in and out of the ring indefinitely, breaking the ring every 3.8sec.
(Press again to stop the script). I have boosted this manually first, but this is so much easier!
You set up the boost and let it auto-run for 8min.
With the correct placement of the dummy you'll get around 24,000 points per round (8min incl loading). So,
180,000/hour with minimal effort on your part.
int turbo = 0;
main {
if (event_press(XB1_Y)) {
turbo = !turbo;
}
if (turbo) {
combo_run(Turbo_1);
} else {
combo_stop(Turbo_1);
}
}
combo Turbo_1 {
set_val(XB1_LY, -400);
wait(984);
set_val(XB1_LY, 400);
wait(1310);
set_val(XB1_X, 0);
wait(1500);
}
About fine-tuning the placement:The best position for the dummy is very close to the ring. But please be aware that the dummy will - over time - move a little bit forward. So, you'll have to readjust him every few minutes. This way, every time the winning team capture back the ring, only 1 second will be added to the score before the dummy breaks the ring again.
However, if you'd rather leave the dummy completely unattended for the entire round, just leave him a couple of steps farther away from the ring. This way, even though he creeps forward every few cycles, he will still be breaking the ring for the entire round. However, when doing it this way, sometimes 2 seconds may be added to the score after each break, and therefore the round will be a little bit shorter, with a slightly lower XP yield at the end.
The reason behind this is that the forward and backward acceleration of the Gears characters differs initially and then plateaus off. It is certainly possible to perfect the script below by changing the "wait time" values, but it is tedious and not worth it, in my opinion.
