From what I've seen, take your barbell weight and multiply it by something between .75 and .9. Then divide that by 2. This should give you a ballpark that's fairly accurate.
When I was able to press 275 for 8 reps, the heaviest I could go in dB was 110 each. My left side would die out early at heavier weights with dbs. That's toward the lower end of the ratio I provided.
103 lbs would be .75. And 123 lbs would be the .9 figure, so it was pretty accurate to my specific situation anyway.
Give that a try and see what you come up with. Try your first set at the .75 number and if it's not rigorous enough, try .8, .85, .9
Oh. Just noticed your talk about a 1rm. There are various charts that you can Google to provide an idea for that.
Oh sweet! I tried googling it and got a bunch of forum posts etc
I'll try out your ratio, I'm going to attempt a 2 plate bench later today, last 1rm was 200
