I use five qualifier tiers:
Locks (QF) are never NQ'ing in any circumstance, potential semi winners (in either or
both votes)
Likely Qualifiers (LQ) won't win the semi, but very likely will amass enough points to place in the top 10
Borderline (BL) are all countries in the dangerzone that could swing back and forth depending on their live.
At Risk (RQ) are probably NQ'ing but could snag a spot if multiple countries in BL and LQ fuck up.
Dead on Arrival (NQ) don't stand a chance.
With that being said, here's my tentative divide (assuming Belarus withdraw) before the running order (the order in which the flags rank inside their respective tier doesn't matter)
Semi 1:
QF:

,

,

LQ:

,

,

,

BL:

RQ:

NQ:

Semi 2
QF:

BL:

RQ:

NQ:

I'm not nearly arrogant enough to dare predict jury and televote winners.
San Marino is such bizarre case though. If Flo Rida is physically there, San Marino are QF because they're winning the televote. If Flo Rida isn't there, but is well integrated into the stage show, they're LQ, qualifying on the back of an excellent televote score. If Flo Rida isn't there or he's poorly integrated, they'll be RQ, finishing lower top 10 with the audience and below 10th with the jury. So I'll just settle with BL and be done with it.
