Azrael360: Yes, only integer (whole) numbers and giveaways made only for the group count when checking the numbers given by SteamGifts. Numbers are rounded down.
oasis789: If rounded down, my winner is above the #9 limit. What should I do?
I think I know who the winner is (starts with "M"?). If it is him, and taking in consideration the old group too, he actually sent 4 gifts in this group (2 were for the old "v1-v2" group), so his allowed gift difference is -7 (right now he has -7 (v1-v2 included)). Although it won't show using AdamBiser's script, after accepting your gift, he will actually have red numbers (because fo the included v1-v2 group stats). This doesn't mean he will be kicked from the group immediately, as for any other member who has red numbers, they have at least a month to fix their negative numbers. Although if during that time they continue to win and not showing any appreciation for the group or otheir members, they can be kicked at any time to avoid more issues with problematic members (as it has happened in the past).
I'm more worried, though, for the lack of activity of this member. Can't find any trace of him for the past couple of years around here. After this, I guess this is it for him, if he doesn't show up and do something for the group in the next month... :(
