The following are what golf handicappers call differential values. I've
listed 25 of them. To compute my golf score handicap I need to take the
average of the lowest 5 of the last 20 of these values, and multiply that by
0.96.
The way I see it, the lowest 5 are 5.55, 6.59, 6.59, 6.59, and 7.64. The
average of these 5 would be 6.6.
Any way I could use my Excel 2003 with some formula?

11.82
13.92
14.96
8.68
17.05
19.15
