I have in hand, The Nautilus Book, that I purchased in 1990. 
On p. 274, there’s a table, “Nautilus Strength Ratings (in pounds for 10 repetitions).” Followed by a simple formula to calculate ‘Superior’ ratings – add 20% to the ‘Excellent’ weight.
The ‘Superior’ strength level strikes me as a worthy and motivating goal.
I’m currently using the big 5 multi-joint machines:
- Pulldown
- Overhead Press
- Compound Row
- Bench Press
- Leg Press
Of those, your table only includes a rating for Pulldown.
However, on p. 271, there’s a table, “Starting Weights for Beginners (in pounds).” I noticed a pattern that one could take 3.5x the ‘Starting’ weight and it would often equal the ‘Superior’ weight. Using a 3.5x factor, one could guesstimate a Superior rating for Overhead Press to be 175 pounds and for [Duo] Leg Press to be 245 pounds – sounds right?
Since a Superior rating on Decline Press is 216 pounds, one could guesstimate Bench Press to be something like 10% lower; so, let’s say, 195 pounds – sounds right?
To fill in the final gap, do you happen to have an ‘Excellent’ (or ‘Superior’) strength rating for Compound Row?
