Kyle the only way to test 1rms is to get under the bar and do a 1rm. You cant claim a "predicted" 1rm.
Absolutely. But the point is - though I didn't express it well - that it doesn't actually change the overall picture.
A person who is overall untrained, novice, intermediate, advanced or elite, whether you go on their 5RM or 1RM, you'll get the same overall level across several lifts, unless they're leaving something behind in development.
I think that's one use of the chart, to remind us where we ought to stand. Most of us know we shouldn't squat less than we bench, but some of us need the reminder; and most of us wouldn't be sure whether (say) a 200lb deadlift was out of whack with a 270lb squat or not.
I say this as someone who pushed up his bench as far as it could go without strengthening back, and so had to start on strengthening legs, too. Knowing the relative amounts of the various lifts if they're to be balanced, this is good.
It's also useful to know what is a reasonable rate of progress. If you believe the e-claims you see on various forums, anything less than a 300lb bench in the first six months means you're a cripple

This is a great chart, but you guys should never feel that your not doing great. I keep telling clients its not where you start.
Absolutely! As I put it: it doesn't matter what I lift today, only that I lifted more, more times or faster today than I did yesterday
