How many constituency seats do the SNP win in your model? I thought 57 seemed a bit low for a 20pt lead

This implies Labour's vote share in Scotland is now back to being lower than the UK total

GE2024: 🏴󠁧󠁢󠁳󠁣󠁴󠁿 35.3% 🇬🇧 33.7%
Jan polls: 🏴󠁧󠁢󠁳󠁣󠁴󠁿 ~20% 🇬🇧 ~25%

Pact is calculated by assuming the 2nd largest projected party (per constituency) steps aside, and ~66% of their voters are willing to tactically lend support

The 66% figure is adjustable but I'll admit, I have no clue what it would be in practice
