I could not figure out how to add words to the image in the comment above.
What I wanted to say was...
"Maybe this chart will help, and perhaps you could save it for use later on."
It is pretty easy to understand & will get ya
"in the ball park", if nothing else.
I likely have some other ones, but thought this one would be of use, and it was pretty easy to find. If I locate some others I have saved up I will share if anyone wants them.
(
Likely, most folks here don't need or want such things, but trying to help for those who might want/need.)
Anyway.
G'Luck~! with your efforts.
Edit to add:: P.S. - the chart is an older one so I would not rely on the "Price" columns. They used to be good a while back, but... You know... I am not gonna say what I should, to keep politics out of it.
