I think the instructions to "not add water before EQing" are just that
the fluid levels will rise as the batteries come to full charge, so you
don't want to end up with over filled cells. I would advise to just
fill all the cells to at least a 1/4 to 1/2" over the moss plates, but
to be a 1/4" to 1/2" below the bottom of the filler tubes.

Hi william
My experience shows me that first filling with water to normal full mark and
then eq provides the best results
Many years ago I had my own battery bank that needed an eq. Newer batteries
well maintained They were low on water but within the normal range. After 2
eq the sg were not moving as much as I expected.
After filling and giving it a few days of normal charging to mix I eq again and
the numbers came out perfectly. Every battery I’ve done this technique with has
worked well.
It was explained this way to me.
With less water you have higher acid ratio meaning you need a higher charge
voltage to eq making it harder to achieve. Higher voltages create higher heat
causing more damage to the battery.

My Rolls manual says:
"It is recommended to water the battery cells half way through the
equalization. This is to
assure the water is completely mixed into the electrolyte."
