The ANSI A-300 Pruning Standards state that you should put in the specifications (contract) what size deadwood is going to be removed. That way everyone knows what's to be done. If the specs are for 2"+ diameter deadwood and there is 3" stuff left when you're done - you missed some. If the client says, "Why isn't that 1' stuff gone?" You can say, It wasn't in the contract." If you don't state size, you just leave the whole procedure up to interpretation by the salesperson, the arborist doing the work and the client. Without specs, all three can have a different idea of what deadwooding means.
