In terms of plant growth rates it's correct, not sort of
A faster rate of growth implies implictly that the plant can
grow faster, thus the plant "prefers" that over another location

In terms of plant growth they are.
The focus is plant growth.
By knowing what each does individually and in combination, you
can tailor whatever your goals might be.

Well, try this, add plain sand and jobes sticks only, add all
you want for that matter.
Next try ADA As and EI.
You tell me and make some predictions what will happen over
time. What will occur when you uproot and prune.

Some seem to disagree, but I have research to the contrary as
well as observations. I would argue in favor of this, not
against the water column.

Basically that number is zero and for good reasons.

I'd say most folks have this belief.
Toss a jobes stick into the water column vs deep into the
substrate to see why.
I was clearly able to show why this caused algae, what specific
part in the jobes stick was causing the issues and that the
other ferts we add do not cause algae issues.
We/I did not/would not have learned that if I held such beliefs
and did such methods solely.

No, not really. They need ferts, we add them to the water column
or the sediment or both.
There are no Star trek transport systems or magic involved here.

Ease of use perhaps is the best argument and something is better
