To be honest, I don't think there's any better way of calculating your own rep max than actually physically testing it, like i did yesterday. The only reason i said yesterday's results might not be 100% accurate was because i'd been ill in the week beforehand and so wasn't in my best condition.
I'd say those tables are much more useful for working out the weight you should use for reps, once you already know your one-rep max.
For example, considering that i do 4 reps in a set for deadlifts, and that my 1rm is 162kg (tbh, i don't think it would have been more than a couple of kilos higher even under perfect conditions), then by those tables, the weight i should be using for reps is 162kg * 0.881 = 142.7kg
Which is pretty much the weight i am intending to use next time i do deads, so guess i've got that one about right.
Though obviously, this is gonna depend somewhat on the number of sets you do and the length of recovery in between sets.
