Thanks for all replies. I too am uncomfortable with 20 minute tests, thankfully the Speccies practices where I work do allow 25 minute tests, I have turned down work where 20 minute tests are the norm. I only work at the particular Soecsavers practice for one day a week and for only 3 out of every 4 weeks. I like Warwicks idea and might try that. I am apprehensive to go to press at this stage as I might then find I am not offered work at all. Will keep you posted how things pan out for me.
