I wouldn't ask anybody to do that. I asked my original question not in anticipation of somebody crunching my data (there wasn't enough data to crunch in any case) but simply because I was experiencing what I thought were perhaps signs of excessive pressure from a very standard/modest load and was wondering whether QL would be of benefit in determining pressures under those circumstances. I think my question was answered quite satisfactorily and have thanked those who offered advice. I hope my question didn't come across as being a request to "crunch data". It certainly wasn't the intention.
