How to make this DAX code more efficient (less duplication).

EVALUATE
var __rates =
	SELECTCOLUMNS(
		{.5, 0.333, 0.25, 0.2},
		"GrowthRate",
			[Value]
	)
var __upperLimit = 10
var __output =
	GENERATE(
		__rates,
		var __currentRate = [GrowthRate]
		return
		ADDCOLUMNS(
			GENERATESERIES(1, __upperLimit, __currentRate ),
			"Days",
				round( [Value] / __currentRate + 1, 0),
			"Deaths",
				round(__upperLimit * POWER(2, [Value] ), 0 ),
			"Country",
				COMBINEVALUES(
					" ", // delimiter
					"Every",
					round(1 / __currentrate, 0),
					"days"
				),
			"KeyFactToDimStartEnd",
				COMBINEVALUES(
					" ",
					"Every",
					round(1 / __currentrate, 0),
					"days",
					"-",
					round( [Value] / __currentRate + 1, 0 )
				)
		)
	)	
return
	__output
