No, because 18 hour LC isn't even in effect yet (starts June 2). IA's are generally going out for 2 reasons. First is that something pops up very short notice, roughly under 2 hours to report, and there's basically no time to run the full ladder. ARCOS batch limits mean they can only call 5 people every 15 minutes for WS/OOBWS/GS, whereas with an IA they can blast basically everyone in the category who is legal. The second thing that causes IAs is that a trip pops far enough out so the batch size is extremely small, or only 1 pilot every 15 minutes. But then it has to call 60+ people with slips in and even as the report time gets closer and closer ARCOS is locked into that 4 people per hour rate. Eventually the clock runs out and scheduling just dumps it to IA close to report.

I've said it before, but probably the easiest fix is to have scalable batch sizes the closer in to report it gets. So right now if a trip pops 12 hours to report it's a batch size of 1, and it is stuck at 1 pilot every 15 minutes even if you run up to and past report time. ARCOS needs to be able to increase each callout size on a rolling time schedule. So 18+ hours the batch size is 1. Then when it goes under 18 hours it starts calling 2/batch until 12 hours to report, then 5-12 hours is 8, 3-5 is 15, 1-3 is 30, under 1 hour is 40. Or something like that, make up your own numbers. That would eliminate almost all our IA issues.
