Every figure as published except Card par (derived), which is summed from the card below and shown only where a published figure is contested; a blank cell elsewhere is one nobody publishes.

The Blue, White and Red tees publish a par the scorecard below does not add up to. Both figures are published and nothing we hold settles which one a round plays to, so the Par column keeps the published figure, marked contested, and each tee's own par row from the card below is summed beside it, marked derived.

Plan it in the Studio

Plan Old Top Farm hole by hole, for your game.

Ask in plain words. The Studio draws each hole on the aerial photo, picks a club for each shot from your carries and the way you miss, and shows where a miss costs you strokes. Where a green was surveyed, it reads the slope too.

  • The approach, planned A Studio approach map on the aerial photo: a lob wedge aimed at the island green, its spread drawn as a dashed ring over the water, and the side it most often misses. Example from another course: hole 15, Resort tee, Stadium Course at TPC Scottsdale
  • The green, from LiDAR A Studio green view on the aerial photo: arrows for the slope a LiDAR survey measured, the area a cup could be cut, and the safer side to miss. Example from another course: hole 15, Stadium Course at TPC Scottsdale
  • Every shot, tee to green A Studio plan on the aerial photo of a desert par 4: the driver off the tee and a 7-iron into the green between the bunkers, each shot with its landing spread drawn as a dashed ring. Example from another course: hole 2, Resort tee, Stadium Course at TPC Scottsdale
