How do I reduce the CPU load for this event group?

So i'm trying to have exploration take place via probes that explore, and ive made it so whenever the amount of explored units to actually translate to a explored zone is reached, it makes a variable a RNG wherein the result decides what type of zone is granted to the player.

if im getting more than 5 zones/sec, the game falls behind and cant catch up with the exploration variables. is there a way to reduce CPU load here?

also, the reason i have the original formula twice is so that i can keep a running total count while also sending off the amount to the random number generator section

Don't calculate the same thing twice! Set ExploredUnits2=ExploredUnits. Use ELSE for your DiscoveryMod checks. It will reduce the number of tests, on average, and you'll only need the <= test for all but the first one. Do you really need to test those every tick? If not, use every 0.x seconds.

awesome, thanks for the info. will utilize at least 3 suggestions
