The back-to-back rule only applies if someone else hasn't posted since your last post in a given thread. Scrolling down the page, as long as someone else's post has showed up beneath yours, you're safe to hit reply and make a new post. If, however, you recently posted and no one has replied, you should edit your last post rather than adding a new one. Excess back-to-back posts waste bandwidth and screen space, and make things a little harder to read.
The exception is if it's been over 6 hours since your last post. At that point, the edit button expires so that people can't just go back editing really old posts willy nilly. If it's been over six hours since your last post in a thread, and no one else has replied since then, you are free to reply again without incurring punishment for back-to-back posting.
Reading this last page, it looks like you were editing your previous post even as others were posting after it. That makes things really confusing to read, because you're quoting posts that haven't happened yet from the perspective of a new reader reading things from top to bottom. No need to edit old posts to reply to people posting after you, you can make a new post then!
I hope this helps make things clearer. The jyarz look awesome. A neat benefit that I think hasn't been touched on is that you could throw a couple jyarz together in a backpack and they wouldn't make a loud noise while bumping around together, like naked glass does. If I had known about these back when I first found this forum and went on a vape/accessory spending spree, I definitely would have purchased some!
Keep it up, I'll be making an order sometime in the (hopefully near) future. Thanks for sticking around and making an effort to figure out the rules. Some other manufacturers throw their arms up and give up rather than making an effort to learn how things are done here. The rules are strict but you'll find that they are a large part of what help make this forum a peerless community.
