Wk 1  Tot	Wk 1 Av	Wk 01%	Wk 2 Tot	Wk 2 Av	Wk 02%	Wk 3 Tot	Wk 3 Av	Wk 03%	Wk 4 Tot	Wk 4 Av	Wk 04%	Wk 5 Tot	Wk 5 Av	Wk 05%	Wk 06 Tot	Wk 06 Av	Wk 06%	Wk 07 Tot	Wk 07 Av	Wk 07%	Wk 08 Tot	Wk 08 Av	Wk 08%	Wk 09 Tot	Wk 09 Av	Wk 09%	Wk 10 Tot	Wk 10 Av	Wk 10%	Wk 11 Tot	Wk 11 Av	Wk 11%	Wk 12 Tot	Wk 12 Av	Wk 12%	Wk 13 Tot	Wk 13 Av	Wk 13%	Wk 14 Tot	Wk 14 Av	Wk 14%	Wk 15 Tot	Wk 15 Av	Wk 15%	Wk 16 Tot	Wk 16 Av	Wk 16%	Wk 17 Tot	Wk 17 Av	Wk 17%	Wk 18 Tot	Wk 18 Av	Wk 18%
80	14	17.50	56	12	21.43	19	3	15.79	42	12	28.57	52	31	59.62	14	10	71.43	14	6	42.86	26	19	73.08	32	30	93.75	13	11	84.62	28	26	92.9	34	33	97.06	48	47	97.92	41	39	95	34	33	97	48	48	100	13	13	100	0	0	0

sample data above, The formula is to work out  how many items in the Av column is above or below 10% of the Tot column per week but return only the value for the best week and only interested in weeks 1 to 7.  

In the data above the best week would be week 6.  14 items total this week so the AV column to hit 10% would be 1.4. 10 are in the Av column so this is 8.4 above what is required rounded up to return a value of 9

the formula needs to do the calulation above basically for each week 1-7 and return the highest value.

Hope that makes sense 🙂
