Even as a fellow 6 digit that has that 8* pass badge, I really wouldn't recommend you tryhard for it. The 8* maps are likely too hard for you to either aim or tap, as at that point the bpm tends to get very very high as to avoid full screen jumps.
And looking at your top plays, I don't think you have the aim to hold up 8* for very long, as the only ones I have in mind are all 4mn+ .
Get your 4* and 5* Perfect Combo badges first, maybe even 6* before trying for that badge. And most importantly, practice aim consistency and stamina. You'll need it for much much more than just this
