Here is that other scenario, which is what I do at some of my tournaments.
4 strike qualifying with 2 player groups until 8 or fewer players remain. Then we have a PAPA style finals, 4 player groups playing 4 games, 4/2/1/0 scoring.
The qualifying portion is 1X the number of actual qualifying rounds played.
The finals is 2X bonus of the # of games since it is 4 player groups, so it's 8 games for 16 meaningful games. Added to the actual number of rounds gets me to either 96 or 100% usually with 50+ players.
Caveat, if I only have 6 finalists (now 3 player groups in first round of finals), then the bonus is only 1.5X for 4 games equaling 6 meaningful games, so it becomes 14 meaningful games (6 for semi-final round, 8 for final round) overall.
