Coincidence or not, this scheme is very similar to BuildConv. With all Kradie's activity in TUS and his interests in schemes, it is strange that he doesn't know one of the schemes that is on the front page of PoC community. Sometimes coincidences happen, and reading Shopper Architect's inspirations and acknowledgments (I like when people do this), this might be the case of a coincidence. BUT, I doubt Kradie never seen BuildConv before, maybe BuildConv was in his subconscious.
I admit I have never checked every profile and communities here on TuS.- I haven't checked every scheme that exists on TuS either. I pretty much Ignore most of the things, and only check on things that I personally find interesting.
Years ago, 2016, I tested out a scheme called Girder Roper. I tested it with pavlepavle, but we didn't like it so much, because of the limitation of the game at the time, and my reluctance of using rubberworm.
However, I may have seen or read about Charle's BuildConv, but I didn't think much of it, and moved on. Perhaps this, and my own idea, was subconscious or not. I don't know. This scheme I made, was not an attempt to plagiarize and taker glory.
Imo, these two schemes are different enough to be each independent version. The people I played it with, liked it, and that's all that matter, doesn't it? Give something to the community once in a while.
I also added Charle's version in the scheme page here.
