I think what he is referring to is that T2 got half of the funding from higher pledges.
This.
For fun, I just added up all the tiers above $75 and it totals $31225, which is almost exactly half give or take 90 bucks.
The most pledges in those upper tiers were at the 100 and 400 level. I think they need to offer something as enticing as that "official beta tester" pledge to really bring in the big bucks. The $400 beta tier alone brought in $18,000.
