Great job. This makes me wonder if my plates are funny, now. I just assumed 45 was 45.[/quote]
Most exercise plates are off. Ivanko, York, and Eleiko Competition plates are dead on, but you’ll pay 4$ and more a pound. I’m thinking of getting some, but this tight economy makes me say no.
I’ve heard that 3% up or down is possible. I have 45s that weigh 43.5 and 49 pounds. Let’s say you have 12 45s on there that way 40 lbs a piece. 4 x 12 = 48. your 585 attempt is actually 585 + 48 or 633. This is extreme of course. Some will be on, some will be light, some will be heavy. My 12 45s weigh a total of 14.5 lbs heavy.
I weighed them when I tied an old pr years ago. I decided I was getting a pr that day even if it was a technicality. the five plates on each side were 7.5 lbs heavy. So my 515 became 522.5. My friend called me gay.
I deserved it. but this is good for your own personal knowledge in attempts for meets. If you know your “315” bench is 321, you have some wriggle room when they’re using competition precision plates. don’t count on this factor if they’re using gym plates.
