Re: upper/lower case

Thanks for doing the test again. Yes, 145 vs 1.2 seems to make more 
sense, because the looping with the many sed invocations. The previous 1 
vs .22 seemed too close. But you never know. The only way to know is to 
do the test (and hope the test is set up correctly).

Thanks, Daniel
