Here comes a wall of (speculative) text...
I've been seeing this a lot (more than I did last year when FEA opened), and it's got me wondering if they aren't maybe holding back on full FP availability for some reason. New rides, especially ones that are a new concept, tend to have a LOT of downtime. FEAhad a ton in its first month or so, and every new ride I ever operated did as well. If they're planning for a lot of downtime (during which times any FPs that come up would then be valid for the rest of the day, thus potentially mucking up the whole system if they have, say 3 hours of downtime and then all of those with FPs showed up in the same hour) then it makes sense that they would limit the number of FPs that are issued as a way of helping achieve a more even affect on standby lines.
Another thing in play is that new rides often don't run at full expected capacity (that is, the number of riders they expect to serve per day, divided by hour) for awhile after opening, and sometimes they never actually reach the full expected capacity due to to some little hitch that nobody foresaw. It's highly likely that capacity is the main determiner of how many FPs to issue per hour, so if they aren't yet running at full capacity then they would be issuing fewer FPs.
In either case they know that they can't take them back once they're given, so they would probably only issue enough to meet the current capacity, even if they anticipate it going up by August or whenever. If that's the case then when it goes up (either because they've wrinkled out any capacity-limiting issues, or because they've reached a point where the little mechanical hiccups have slowed down) they may issue more FPs, so keep checking.
