		Explanation:
		Total improvement (far right hand column) equals the stroke improvement multiplied by rounds played with rounds played being the lesser of rounds played in
		CY23/CY24.  Stroke improvement equals the CY24 Standard Rating less an adjusted CY23 rating - the CY23 rating is adjusted for two factors described below.
		Below are some examples:
					Nataliya	Nanna K.	Riley			Adjustments:
					Guseva	Madsen	Smith			The Standard adjustment merely puts all golfers on the same rating standard.  If the golfer is in the LPGA group (not Epson), then the postive adjustment is 2.35 in CY23 and 2.30 in CY22 & CY24 and, if the golfer in in the Q School group, then the negative adjustment is 0.40 in CY22, 0.50 in CY23 and 0.45 in CY24.
		CY23 Rating -
			CY23 Group		Epson	LPGA	Epson
			CY23 Group Rating		1.57	(0.25)	(0.10)
			Standard adjustment		-	2.35	-
			CY23 Standard Rating		1.57	2.10	(0.10)
			CY22 Addback		-	0.12	-			CY22 Addback - If a golfer's CY22 overall rating exceeds her CY23 rating, then we adjust the CY23 rating upward by 50% of excess but the upward adjustment is limited prorata based on the rounds played (CY22 vs. CY23).  Below is an example (Nanna Koerstz Madsen).
			Rating adjustment				0.03
			CY23 Adjusted Rating		1.57	2.22	(0.07)
		CY24 Rating -								Round played					Rating adjustment
			CY24 Group		LPGA	LPGA	Epson			CY22 rounds			68		CY22 Rating			2.39
			CY24 Rating		1.18	1.06	1.02			CY23 rounds			80		CY23 Rating			2.10
			Standard adjustment		2.30	2.30	-			Prorata adj %			85.0%		Rating decrease			0.29
			CY24 Standard Rating		3.48	3.36	1.02			General %			50.0%
										Adjustment %			42.5%		CY22 Addback			0.12
		Improvement								In the above calculations, the prorata adj % cannot be greater than 100% and the decrease cannot be less than zero.
			CY24 Standard Rating		3.48	3.36	1.02
			CY23 Adjusted Rating		1.57	2.22	(0.07)
			Increase		1.91	1.14	1.09			The Rating Adjustment applies to golfers that have a negative CY23 rating, afer the CY22 Addback is applied.  The adjustment equals the sum of a) one-third of the amount by which the CY23 rating is less than negative 2.04, plus b) one-third of the amount by which the CY23 rating
			Rounds played -
			CY23		57	80	33
			CY24		67	83	34
			Lesser of two years		57	80	33			is less than zero.  For example, if a golfer's CY23 rating is negative 3.13 then the adjustment is a rounded 1.41, this amount being the sum of one-third of 3.13 less 2.04 (.363) and one-third of  3.13 (1.043).
