PPC got 1.6%. Not sure that qualifies as a "vast majority".
Read again what I wrote. The PPC accounted of the vast majority of the "other parties" vote. Besides "the Independents" no other minor fringe party got more than 0.1% of the vote. Most of them got between 0.01 and 0.05%.

1.6% is 2/3rds of 2.4%. That's a majority, but a vast majority.
If we extrapolate that share to the OP's chart, that would mean the PPC is polling at 4.6% in this poll. They polled higher than that a few times leading up to the 2019 election, and still finished with zero seats.
