More fun mental math. Averaging! Take the numbers 20, 30, 28, 25, 24. Average them. Here's how you do it. Take the low number, 20, now bring everything down to 20, whatever you subtract to get down to 20, add to "the pot". 20,30->20 (10),28->20(18),25->20(24), 24->20(28). So now you've got 5 20's and a pot of 28, divide the pot by 5 and add it to 20, the average is roughly 24, closer to 23.5 . You can do this for wider ranges too. If 14 was in the mix, I'd still pick 20 as the base, because i know I have enough to bring up 14. When I'm brining down 30, I'll redirect 6 to bring up 14 and only add 4 to the pot. Is this making sense?
