but this is exactly what you should not do...

(this will take a little time for me ... Thanks

, i reading now)
hey @roland
am I going mental? I read this post from n2n1 and went to reply and the post was different between what was on the screen in his post and what is in the quote part of this email.
now the op is as it is now, but there is no 'edited by...'
the syntax of his first line is different, and the inflection is very very different. if someone or something is "tidying up" his words, no wonder he is getting confused and frustrated.
from memory the original first line read something like
'but not this.... this you should do'
he was referencing the gronks 'I was trying to avoid a technical explanation'. look a the op and substitute what I think I saw there originally.
looking at his location - if he is from Russia - I have known a lot of Russian fishermen who speak very rough English (mostly swear words lol!)
the phrasing of the words I originally saw (said in my head with a Russian accent) would have meant more "Please do give a technical explanation, don't try to avoid it" than a demand to not do something.... way different
I think he is trying hard to understand and learn.
sorry if I am off base, but I swear the post changed....
-->update<--
I will now go and bang my head on a brick wall. hes changed the OP now.
time for a drink.
