let me give an example.

say you played 50 hands HU with an average rake of $1/hand.
you also played 50 hands 6-handed with an average rake of $2.50/hand.

PT way:

($2.5 * 50 + $1 * 50) total rake / 4 APH = $43.75

you contributed $43.75.

accurate way:

$50 / 2 = $25
$2.5 * 50 / 6 = $20.83
25 + 20.83 = $45.83

you contributed $45.83.
