It's hard to tell anything with this mate. You looked like you were sitting back in a strong position for a sumo pull, but it looked like your legs weren't very far apart. However, you can't see much and you're super tall, so it might be deceiving.

Better equation:

(weight * reps * .0333) + weight = ~1RM.

e.g. : 225 * 5 * .03333 + 225 = 262.5 calculated 1RM.

It's fairly spot on within 1-2% in most cases. I use it up to an 8RM and anything beyond that is too many reps to calculate a TRUE 1RM.
