Yes, @tagarisko007, this is a very interesting posts, but the text above in your post ("The rhyme is a rule of thumb...") is from a youtube post, as found by @cheetah above... Did you make that post on youtube? If you did not, you must properly cite any sources that aren't from yourself...

I know I just add it for information

That's perfectly alright--but you need to cite--i.e., provided the name and location of where you acquired/ retrieved any knowledge that was not immediately your own; this includes images. Please edit your post accordingly.

and I clicked this picture

Sorry lol you mean you took this picture? That's great. I would state that in your post too, just for clarity (and so others know who "clicked" it!) . But the text must state the source. Thank you.

Thank you for support
