1/2/11 - 50% G, 50% S
1/5/11 - 50% S, 50% I
1/12/11 - Attempted 50% S, 50% G but it wouldn't let me so I went 100% G.
I think I see what the problem was now. According to TSP.gov I had 56.66% I fund and 43.34% S fund, even though I had my previous IFT set at 50/50. I'll bet this is because I had my contribution allocations going 100% I fund. So yes, according to those numbers it seems that I was trying to bump up the S fund to 50%. I'll be sure to look at that next time.
