[QUOTE="Randy Tidwell, post: 2295345, member: 109136"] JF, I am also confused on the math. I am only doing this as a exercise in math. Using Excl's Standard Dev formula (=STDEV.s(A1:A7), I get 6.1 SD, 19 ES, this matches the Labradar pretty close. I kept shot 9 in the mix, as it was only 3fps slower than the 3300fps average. 3301 3308 3300 3289 3304 3297 3304 Been looking for some N165. Like everything else, short supply. [/QUOTE]
