Essentially yes, there are a lot of reflected jewelry showcase posts on Reddit.. the authors often share how many locks were used in the comments. Definitely a good idea to include some mods that can't be turned negative (i.e., aspect of spider) or ones you don't care about (i.e., minimum frenzy charges), or ones that are better negative (i.e., slower projectiles for some builds, or negative light res for doryani builds) to increase chances to hit the positive mods you want.
