Oh nice, I just woke up to all this, thanks for the comments and likes everyone 
Yep, that SD card started to feel heavy once or twice 
I just looked at the discussion me and @Joe had while working all this out and there are 270 messages. To be fair @Joe did a lot of the leg work actually patching it up, I was smashing and breaking it as much as I could, finding problems and we both came up with solutions all the way through the process. This eliminated a lot of versioning problems because the files were generally going one way.
I really mean what I say about neither of us being able to do this individually, it really was a team effort. We’ve worked together on quite a lot of things over the years and have established an excellent rapport, considering we have never actually met in the ‘real world’ I think we’re doing alright. @Joe wrote almost all the documentation, I drew the graphic and converted the docs to the WIKI.
I think the biggest challenge was to get the gain staging across the whole patch right, but we think we have found a nice balance with reasonable constraints.
I’ll say again, we loved every minute of working on this … Thanks @Joe you’re a star!!
