Fixing the effects of Yahoo imagery misregistration (part 2, south-west Brisbane)

I'm currently on the next tranche of feature alignment to local GPS traces. Areas covered this time are parts of Goodna, Richlands, Forest Lake. I'm sure itoworld's OSM Mapper will tally the exact cost in a day or so.
To recap, I'm realigning features from their apparent position in Yahoo imagery to their truer position compared to GPS traces in the area, an error of about 20 metres.

Map looks nice.
AFAIK Yahoo imagery has accuracy up to 30 metres.
