I like Matthew's (Blue Apple Herps) simple formula. No messing with scales. However, a lot of people, especially when doing something new, like to have the instructions carefully spelled out for them in detail, in the way the Munson plan is written.
Comparing the 2 does bring up the question of whether a snake with a relatively short, fat body-shape can eat more than a more slender one that weighs the same. I'd assume a snake with a bigger girth would show less of a lump. On the Munson plan, the 2 snakes would stay on the same size meal regardless of body type, while on Matthew's plan, the girthy one would move up in size sooner.
To get to the OP... the Munson plan specifies "-When they're on single pinks (2-3g), I feed every 5-6 days. (Snake = 4-15g)" I interpret that to mean the OP's 8g snake can eat 2-3 grams of pinkie, so it should be able to eat 2 of the 1g pinks (assuming those are accurate weights). Obviously, we do need to use a little common sense here, though. I'm pretty sure no one would recommend feeding a 3g pink to a 4g snake, even though that is within the ranges in the Munson plan.
If the OP ever said how often he is feeding his snake, I missed it. If you are feeding once a week, you could step up to 1 pink every 5 days, and that might be best until the snake grows a little more. As Wade pointed out, there really is no harm to sticking with 1 pink for a while longer. On the other hand, increasing the size of the meal too much or too soon is potentially dangerous to your snake.
