that seems overly elaborate. he isn't looking for speeds carried out to two decimal places, just seeing if his speedo is off.
i guess if that was the point, i can tell you right now. yes, it is, every speedo reads a bit high. but also your tires are 9.26% larger than stock. so in fact it reads low. to maintain the stock diameter you'd need a 245/35. or a 235/35 would be closer yet.
