I lift weights for twenty years and I have never heard 6 reps of 525 equates to 610...what kind of mathmatics is that? A baseball coach once said that "baseball is 90% mental and 50% physical"...you and that coach have something in common. They don't put estimates on the board at OSU, please check your source. Hey Tibor, if someone stands in the Seven Eleven where you work and drinks a 16oz Coke and all the three refills, do you charge him a six pack???
It's One Rep projections are actually very common
here is a pratial cut out from
http://www.criticalbench.com/chart.htm
Maximum Lift Reference Table
The following is a chart that can be used to determine your projected maximum without performing a 1 repetition max. Some athletes "get psyched" for a maximum lift, while others get psyched out by the number 300,350, or 400. But as a rule, the chart gives a good indication of what an athlete is capable of for a single lift. Example: The first column all the way to the left is the weight that you are using. So let's say you use 135 lbs. If you can bench 135 lbs for 8 reps than your estimated one rep max is 167 lbs. So just slide your finger across the page and line it up with the number of times you can lift the weight. Yes you can use this chart for other lifts such as the squat as well.
