Maximum rounds per card = 3 rounds with your bud.
I have some

ideas:

black & white & shade - economy print

add address/GPS to park/town

remove date area, either show course record(s) & update as required(3 row/player, 2 column/tee) or have area for writing in tourney name.

integrate par rows
- 6 ABC rows can make 3 ABC, then split top/bot(to 6) for blue/red tee rows(white/shaded) use smaller font(maybe different) for par amounts
- eliminate bot row to increase height of 3 ABC rows (to split)
- empty bottom 3 rows ABC(now 2) makes 8 total = 2 rounds/4 players, 2 player/4 rounds, 5-some now, 3-some later, etc.

label blue/red/player column for round number/date(personal use = 8 rounds)

show yard totals(front/back/total) where blank(6 rows ABC)

move total column off sheet edge
Maximum rounds on each card =
4 rounds with your bud!!
