Polling day is here, and so is the final BBS projection. Certainty? I don't know her.

Projected Seat ranges:
SNP ~ 58 to 71
Con ~ 24 to 32
Lab ~ 18 to 25
Grn ~ 5 to 11
LD ~ 4 to 8
Alba ~ 0 or 1 https://ballotbox.scot/sp21-final-projection

For Twitter-only folk, here's the full image!

Though the ranges for each party look wide, note that the minimum case for them all sums up to 109 seats (~85%). That means I reckon only 20 seats (~15%) are really in play!

Let's look at each region in turn for more detail...

Central Projected Seat Ranges:
SNP ~ 9
Lab ~ 4
Con ~ 2-3
Grn ~ 0-1

With apologies to the good folk of Central, probably the least exciting region this time. No obvious battlegrounds, the one shuffle may be for a Green at Conservatives expense.

Glasgow Projected Seat Ranges:
SNP ~ 8-9
Lab ~ 3-4
Con ~ 1-2
Grn ~ 1-2

Kelvin: SNP vs Grn, likely SNP
Main competition here is on the list seats, with prospects of doubles for both Con and Grn putting pressure on Labour's 4th seat.
