Couldn't you have a happy medium while using 1-4 4-8....draw a happy medium,wanna get critical? 1-4.5" 4.56"-
That is just asking for problems. And shows customers that you really didn't put much thought into writing the contract. The first thing a customer is going to do is ask "what if it snows between 4.5 & 5?" In court, a lawyer would make you look like a fool. And your contract would probably be determined to be useless.So you go to 4.5 " & 5" .
