The Ptarmigan Course Handicap (PCH) App allows players to view their relevant scores at Ptarmigan. All members of the men's club (PMGA) will use their PCH value for all competitions at Ptarmigan. PCH is computed using 4 different sets of player scores:

1. GHIN Index - All scores, home (all tees) and away posted to GHIN (average of the lowest 8 out of the last 20 scores).
2. Blue Tee Index (BTI) - All Ptarmigan Blue Tee posted scores (average of the lowest 8 out of the last 20 scores).
3. Competition Score Index (CTI) - All PMGA tournaments or other defined organized "competitive type events". Examples -- Friday Nooners, PMGA Matchplay brackets, etc. CTI is the average of the lowest 8 of the last 20 competitive scores. All tee boxes apply here.
4. Low Handicap Index (LHI) - computed and tracked by GHIN. This is the lowest handicap index that a player had during the last 12 months.

After logging in to the App, the players PCH will be shown, indicating which criterium was used to create the value. Members may view all their scores that were used to compute their BTI and CTI values. The App will also allow players to look up the PCH value for any other member of the PMGA.
