It all depends on what point you want to stop playing around and actually 
use the item.

In a PS all you really need to know is the Lmin requirement.  Traditional 
engineering wisdom says to not use a
L that is right on the edge of the calculation but select one that is ~ 2X 
Lmin. Now use the cheap generic
LCR meter to select a choke that complies, install it and quit dragging out 
the drama.

The charts and graphs are fine for predicting how it will work in use. 
However if all you do is talk about it
that point is never reached.

I worked in EE labs most of my working life, from tech to EE. It was always 
a battle getting engineers
with no bench experience as a tech to release a design to review much less 
actual production.
When I was in a hiring position I never went with an EE that didnt come up 
thru the ranks on the way to his degree.
I was also biased to those with Navy or USAF tech school experience where 
they taught
common sense. The end result were products that came in on time or under, 
well within budget, and with minimal hassles
getting thru the various manufacturing engineering processes. My boss looked 
good, I looked good and my group looked good. That translated to nice pay 
raises for all.
