Leupold Varmint Hunter?s Reticle sync

Hi everyone,
Each Leupold scope with Varmint Hunter's reticle has 2 special markers on the power "dial":
Small Bullet Drop [SBD] and Large Bullet Drop [LBD].
What they mean is quite obvious from the scope manual.
On 4.5-14x scopes the [LBD] marker is on the maximum magnification.
It means on 14x (or to be precise on 14.4 according to the scope specs).
The ratio in numbers between [SBD] and [LBD] is 1.25.
It means that [SBD] is on 11.5x power.
What I'm trying to accomplish is to recalculate the drops (in MOA)
on the maximum power on my 6.5-20x scope, knowing that
the actual maximum power is 19.6.
It means that the ratio between LBD marker and the maximum power
would be 19.6/14.4 = 1.361.
Using this ratio I can recalculate the drops for each horisontal bar on the
reticle at maximum power...
You probably wonder, what exactly the question is
My question is if my assumption that
[SBD] and [LBD] markers are on 14.4x and 11.5x power
is actually correct.
Thank you so much in advance!

That's one thing I still liked about Shepherd scopes. It's already done per cartridge, and it's more accurate.
Great fun. I found that I could shoot that bullet nearly 200 fps faster then required for the markings. I loaded it down.
Finally realized that far preferable is to take whatever load you wish to shoot, range test to the various markings, and make a range card.
Deer hardly ever step out at 300 yards, anyway...278 yards, perhaps, or 325 yards...
Thank you for your replies!
I ended up learning that my assumption as a matter of fact was wrong.
Just a day or two before I posted this question here I sent it to Leupold guys.
They didn't reply immediately and I decided to ask here.
But eventually their reply has arrived.
Here it goes.
...the large triangle on a 4.5-14 is on 14 power and the small triangle is on 12 power,
for the 6.5-20 the large is on 16 power and the small triangle is on 12 power...
But then
SBD/LBD ratio = 1.25, that you can calculate from their drop numbers in the manual, doesn't make much sense, does it?
14/12 = 1.17
16/12 = 1.33
The calculated from the drop numbers 1.25 is in between.
Well, it just convinces me once again to make my own measures and forget about what they and manual say.
