October 2018 PQP Result & How Close Was Our Prediction?

So this was our COE PQP prediction for October in a post just a few days ago:
Cat A $30,784
Cat B $32,436
Cat C $29,513
And this is the actual PQP
Cat A $30,284
Cat B $32,278
Cat C $29,397
This is based on the latest six rounds of COE bidding used to calculate the PQP for October.
We were right with the good news that PQP prices would be lower across the board! The actual reduction in PQP for the three categories are:
Cat A $2,055 savings over September
Cat B $1,098 savings over September
Cat C $1,300 savings over September
Congratulations to those who waited! Especially for those who have vehicles in Cat A, with a savings of over two thousand dollars!
And how close are our prediction compared to the actual?
Cat A $500
Cat B $158
Cat C $116
Were we close enough?
