How long do you spend nursing?

My daughter is 6 and a half months old and from the start she fed for usually around 20 mins on one side. We are doing BLW and have been for about 3 weeks. She is eating a lot! She still nurses the same number of times but s now super quick. I still time all of my feeding sessions and the past week the total time spent nursing is down to under an hour a day. Does this sound like enough? Time spent has literally halved! She does seem fine and is still sttn. 

I'd be interested to hear others experiences since solids have been introduced.
