Hi Dave.
First off i hope you, Paula and the family are all OK.
As you know i,m am dylexic,so some of my bluntness stems from this. I wish i could post eloquently like you but that would take far too long.
As for only working on system i understand, that is pretty much true, fully understanding them, well that may be not so true .
Also as you know i,m an old git , so my need to earn is most likely less than most , so my learning time of late has increased, but i have always tried to learn as much as possible that is why i have every technical bulletin Peter Coombs has produced, most of James Dillon's work etc.
Plus i never mind going on the many pay to view manufacturer,s info system,s.
As for me being HONEST i do try but it is too easy to stray but the above is pretty much true.
All the very best MATE
and give Paula a kiss from me
Kev
