Mr Chairperson, basically if I read to you minimum and maximum time periods in the case of one, it says a minimum time of 15 minutes, maximum time of two hours and average time of 45 minutes.  In another case it says at 10 degrees for the red, 10 minutes to four hours and 40 minutes, with an average time of one hour and 45 minutes.  One can see that there isn't any great deal of accuracy at all.
