So what's your guys' take? If a program only requires 2 is that the number we should send? What if it turns out that the 3rd or even 4th letter is a little stronger?
Do you count the MSPE and the "Chair Letter" in these 3?
If a programs website specifically says they want 3 letters of recommendation are they going to throw away my application/be annoyed if I send 4 letters?
Where do you exactly find our how many letters a program wants?
