Letters of Rec

Hi everyone! I am a little confused, need some clarification! A good mentor of mine has offered to write me a letter of rec. I prefer this letter of rec over another one (we’ve been working closely this past year and I’ve deferred applying for the 2026 cycle instead of this current one), meaning I have <4> LORs. I don’t intend on submitting 4 at once, but I do like options . . . . . If my mentor writes me a 5th LOR, is there a limit to how many LSAC can receive? Again, I am not submitting all of them but she has one of the best testaments to my character as she is an attorney I have grown professionally close with / worked her files / helped with depos etcectec
