180, as in anything, there are good ways to do something, and there are..... the other ways. Each league will be set up differently, and, I guess, it depends on how the lane wants to do it.
The USBC does have a recommended procedure. But, there is nothing mandatory in explanation or the how to side.
My first PBA session had the local Pro and the House Laneman in attendance each night. The Laneman gave each of us an oil pattern chart, and explained it fully. The local Pro talked with us as to how best to play the lane and what various Pros do on each patter. Other leagues in my area actually have Pros running the PBAX league. A couple of them bowl, but the successful ones actually had the Pros walking the lanes where you could ask questions, get help reading the lanes, and get suggestions. They were also available afterwards for personal assistance.
The leagues run with a Pro in attendance were the most successful ones, and have grown in participation. Many, who just threw bowlers on the lanes and said GO, have failed.
It is advisable that any one you partake in have some instruction with them. That way you benefit the most on the condition and with a watchful eye looking over you. Remember, this is to be a learning experience for you. You will learn faster with instruction, rather than by trial and error.
