OK, I thought that was what you were going to be simplifying...

I did have a poke around in there some time back and it did feel "quite 
complicated" to follow what was going on... I found your sql backend 
code as a simpler way to poke around, but even there it was pretty 
quickly going to need some earnest digging to figure out how it was all 
working...

OK, I guess this can never be an easy middle ground - presumably things 
are as they are for a reason...
