The committee advisor at my school said she had dealt with them before, and thought just the committee letter EIF (it's different than the ones ind. prof.s get) was fine, but she wasn't 100% sure. I went ahead and filled out the 3 required fields on the EIF page, 1 committee, 2 individuals, printed them, and gave them to my advisor. She said she would call and if they absolutely needed the 2 independent EIFs, she would give them to the 2 ind. prof.s I designated and include them with my packet. Also, my advisor said the committee letter, and all attached ind. letters of rec count as one letter, so there's your door to get more than 3 in.
