Ooh, this is all very good!
Carlson: "Gold Points can be exchanged into Avios in increments of 10,000 GPs into 1,250 Avios or in 2,000 GP increments at the rate of 8:1"
This is not entirely right, it is a sliding scale:
Points Miles Earned
2,000 points 250 miles
50,000 points 8,000 miles
100,000 points 18,000 miles
Feel free to delete this post after making the change!
Perhaps worth mentioning that for the last 3-4 years BA has done an annual '25% bonus on hotel conversions' promo
