As someone that both likes and hates the new system (it has its perks and setbacks from the way releases were done before), this is probably the fairest system that could work for pin traders (old and new). As for the comments that it helps families (it does and doesn't) I can relate as I go alone BUT we have to remember that pulling a number after one another means these "events" (pulling a good number) are dependent on one another.
SO to make it simple, let's pretend there is an LE 5 release and 10 people show up, so 5 good numbers and 5 bad numbers.
The first person has 50% to get a good number.
If the first person picks up a good number, the second person now has 4/9 chances (44%) to get a good number; This is a little less than the first person.
If the first person picks up a bad number, the second person now has 5/9 chances (56%) to get a good number; This is a little more than the first person.
If you continue and continue, you notice that your chances of pulling a good number vary from person to person as they get a good or bad number and the overall pool decreases. So families/groups have MORE chances to pick a number but that doesn't necessarily mean that they have a better chance of getting a good number.
