%age is useless. It is a simple formula. Its a countdown to 180 days from your R10 Date (usually MEP/BIL date). Don't worry about it being 1% or 99%.
No clue on VACs, did you call VFS folks ?
not so fast sir, it only means that eligibility is passed as per the candidate. That’s your declaration. Wait for a month after MEP/BIL to get the real status
