It's clearly wrong to multiply full attending members * 5 Except that's the standard for gate.
You don't have to like the standard, but that is the standard, at least, as I've encountered it in use. These large events don't try to count bodies actually present, except for fire code compliance. They count paid-per-day-to-attend.
If you want to compromise on it a bit (it'll make you look smaller against the standard, but this is fandom, after all), then you could count starting at badge pickup. Someone with a five day who shows up on day three would count as three (Days 3, 4, 5.)
Many of these large events don't have badge pickup - they're posted off in advance - so they can't do that kind of check. But Worldcon could. So start with badge pickup (the one solid piece of data you have), include that day, and all days to end of convention (for full memberships), then add in all the one-days as one each.
