Re BIB.I'm not sure I understand your question.
You say 10 minute spacing helps, but that means less tee times available, especially in the winter.
So more people after fewer slots.
If you want to play earlier in the day, get to the booking system earlier before all the spaces go.

Organise your life better so you can play later.
The golf club doesn't revolve around one person.
Personally I would have 8 minute intervals and close the sheet 5 hours before dark.
As a golfer with a high handicap, some people might argue that I might play slowly due to taking more shots. Therefore, under your preferred system, I wouldn't be allowed to book an early tee time. However, the golf club shouldn't solely revolve around fast players. In club competitions, if most groups complete their rounds in a similar time, say 3.45, 4.00, or 4.15 hours, that should be considered the standard. Faster players should anticipate this and perhaps play with someone of average speed to moderate their pace. Slower players should be encouraged to pick up their pace. Additionally, allowing groups to play through can significantly slow down subsequent groups, adding 5-10 minutes each time.
