I don't play as many as I used to, but for a number of years, we corporately played in a lot of scrambles. You start getting into strings, throws, and blows, the numbers can get ridiculous. Won a few over the years, seen some serious cheating in front of me, but where I have seen the most blatant cheaters, the winners donate their winnings back to the charity.
Here is the deal with a scramble. Drink beer, play with good friends, have fun, expect to go home with nothing, you are supporting the cause.
And for those who said the drive was the most important part of a scramble, I disagree. It's the approach shot. 12" or less putts are the key to going low in a scramble. Fairway versus rough is not important, you place the ball, don't drop it, so you can get as good a shot from the rough as the fairway. I would take 100 from the rough versus 130 from the fairway all day in a scramble
