You're welcome. when I said stringer I was referring to the person not the machine, Just a joke. LOL But you can look at it this way when you're stringing a 16x19 there are about 25% more crosses than mains, and because the crosses must be fanned through the mains it will generally take a little longer (let's say 25%) to pull the crosses through than it does the mains. So you crosses should take you about 50% longer to string a racket than the mains do plus the time it take you to weave the crosses. So it it takes you 8 minutes to string the mains it will take about 12 minutes to string the crosses plus the time it takes you to weave the crosses assuming you don't tave too much of a problem with kinks, blocked holes, etc... Do the math for yourself and you will get an idea of what your time could be. Then you have your knots which also adds time.
