http://www.popeofslope.com/scramble/index.html - Handicap each team as follows: 20% of the A-player's handicap, plus 15% of the B, 10% of the C and 5% of the D. Add the results, round off the total to a whole number and that is the team's handicap.

1(20%) + 14(15%) + 15(10%) + 16(5%) = .2 + 2.1 + 1.5 + .8 = 4.6 = 5

2(20%) + 10(15%) + 10(10%) + 26(5%) = .4 + 1.5 + 1.0 + 1.3 = 4.2 = 4

Calculate each player's course handicap, which gives players a different number of strokes to compensate for greater or lesser difficulty of a course. To calculate your course handicap, multiply your handicap index by the course's USGA slope rating, divide by 113--the rating for a course of average difficulty--and round the answer to the closest whole number.

For four-person teams, the suggestions are 20 percent of player A's handicap, 15 percent of player B's handicap, 10 percent of player C's handicap and 5 percent of player D's handicap.

And a long paper at:

though you need to contact the authors for the Excel spreadsheet to calculate the team handicaps (and apparently is better than USGA emthod above (20, 15, 10 and 5 percent)
