Bloodlust advice

Hi everyone, I’m just wondering if anyone here who has beaten bloodlust could answer some questions. My current hardest is bloodbath, and I am leaving for college in 4 months so I thought I’d try to complete my dream level before then.

1. What is the best refresh rate to use? (Fps, tps, CBF etc)

2. I currently have a best run of 42-80 on 144hz (no cbf), is that at all good? How much of a from 0 grind is BL?

Basically wondering if there is any chance at all that I could do this in 4 months, keeping in mind that I have lots of free time and could play 3 hours a day. Thank you!!!!!!!
