So basically with the standard deviation, you get rewarded for being more consistent in your rounds? Also, when I am trying to figure out my standard deviation in excel, do I include the round that is subject to being dropped or not for calculating it or no?

From there, I multiply the number that comes up by 2.5 and if my round is more rating points away than that it does not count. Is that correct?

Also, when figuring this out, do you use my previous updates rating or how does that work? Because right now my SD is only 20.49 which means I could shoot a round 51.225 worse than my rating and it would drop?
