In the game stats (next to the scorecard), the stats for scrambling and sand saves can be mathematically incorrect.
If the player has made all greens in regulation or avoided the sand, the stat given for scrambling or sand saves is "0%".
However, when the number of instances is 0,
the stat is 0/0. You cannot divide by zero. The answer is undefined, not
"0%". It should be presented as -- or as "N/A".
A similar situation could arise with respect to other stats, such as driving accuracy. If only tee shots with the driver are counted toward driving accuracy, then a player who tees off with a 3W or iron would have a stat of "0%" when in fact the calculation is 0/0, that is, -- or "N/A".
