there was no point in making a savetable, as the values change each time. Just search 4 byte interger for you current amount, say 4/4 helicopters search for 4, send one to an enemy base so its destroyed. filter results to 3, then wait till another is built, filter to 4 again, keep going till you filter them down till you have between 3 and 5 results, then freeze them all to 1, and your bases will keep producing them.
As for health, thats a flaot value, its best used on units with mroe health, so you have mroe tiems to filter the hp before its destroyed, the zeplings are goo, but helicopters work well too, i made a group of immortal helo's yesterday, and sent 1 to each platform to slowly take them over, and then protect them.
