you can either callibrate it based on individual results or you can callibrate based upon league-wide results and then anything in between those two choices that you can think of.

basically we can't affect distribution of ratings much -- that determines how much of the pie that person is likely to get, and over time will get. a dearth or saturation as possible exclusions, a guy who is ~125% of league baseline will continue to be 125% of league baseline after most any change. (again*, extremely small or large League Totals may not adhere to this statement, same with anything that drastically changes distribution of players, like too many or too few causing an significantly smaller/larger # of better players than normal.. a dearth over time may still 'add up' but any one year could be barren)

volatility amounts to a fairly consistent percentage of baseline, and when it's a larger range, the slices get larger per '1-pt' rating change = greater variation between good and bad. (*** similar exclusions as above, assumes staying 'in the ballpark' relative to previous settings)

i care about both, but i will fudge a little on league-wide resutls to get individual results that i want to see. mainly peak performances and how often they occur. whatever your opinion on the matter is, you'll likely have to compromise on something.
