I am lost a bit for words, just looking at it makes me nervous and envious. Nervous because I do not really understand it & envious because I do not really understand it.
Being just starting on grade 2 it`s like some sort of alien language. I might be able to understand it properly in about 10 years (possibly). Well done Richard for doing stuff that seems improbable, this is only one of a lot of “alien” things that you are really good at.
I doff my hat to you, well I would if I had a hat.
