Im also a newbie when it comes to mapping but i think 175 bpm exactly and 1.740 offset should be good to map most of it. you can do fine tuning later if you notice the rythym is off after a +-30 sec
God damn rhythm is off after 10s xD Thank You for help, i'll do my best :v
@edit
Oh i know what was wrong. The song is changing these lines in snap divisor dunno how to call it im stupid pl. So i just put sliders and circles one "snap divisor" closer(at 1/8)and everything's okay for now.
