For a golf course, this is undoubtedly the most difficult modality to implement. You must play very accurately or hit short on both tees, these are your safest options.
If a golf course chooses this teeing method, the start time is controlled very carefully, also because it is quite risky. Sometimes there are problems, for example, it can happen that 3 games wait because tee 10 cannot play because tee 1 was too slow.
But what you usually find are successive tee times at Tee 1 and Tee 10 in 10-minute intervals starting at 9:30 am and then there will be a second start time, after the time it takes for a round of 9 holes.
For example: …if it takes about two hours to tee off for nine holes, it looks like this:
Tee 1 – Tee 10: 9:30 every 10 minutes
Tee off: Tee 1 – Tee 10: 11:30/ every 10 minutes
So the last round starts at 13:30 and all players are finished at 15:30
