How long will the RR6 last?

I am stuck on section 3 right now and i am not sure if i will be able to beat it before getting better IDs (i used up all my main IDs in section 2 without knowing that they will be blocked).

Oh and also a question, will both of the teams i used for section 2 and section 3 will blocked for section 4? Or my first team i used in section 2 will be unblocked?
