TR question regarding graduations on adjustable "super cooper" foresight

[tattless_tradie]

I've newly acquired an adjustable Super Cooper foresight. I get the idea; you mostly adjust the front sight instead of the rear, leaving your comb height largely constant.

QUESTION: what metric does the graduations represent on the aforementioned sight? If it's in MOA, then I've only got 15moa to play with... when i technically need 20+ out to 800m (with a 300m zero). But does it simply mean I have to start adjusting the rear-sight elevation beyond 700m (i.e. if i need more than 15moa provided on the front sight)?

It mentions on the cooper website the graduations are in "100m graduations" - but this can't be though because the graduation spacings seem to be constant?

Cheers,
Jim.

Oops I think I submitted to the wrong category

you will need to sight it in and achieve a lower number for 300yds so as you go forward you will utilise all of the graduations.
at 1000 yds the sight will be at the lowest point,
usually each graduation is 6 degrees but some are 5.
good luck,

Thanks budget - realise i messed up putting this in the F/TR category...

So the graduations aren't "minutes of angle" aka points? I'm only running a 28" so I realize this also plays a part but am I right in understanding that if each graduation is 5/6 "degrees" so to speak, we are talking around 5/6 points/moa per graduation? That's a lot - i'd only need roughly one graduation per 100m delta? (yes it's non-linear i know but close enough)

i.e
300m -> 500m = + 6.5moa = -one graduation on the cooper!
500m -> 600m = + 4.0moa = -one graduation on the cooper!
600m -> 700m = + 5.0moa = -one graduation on the cooper!
700m -> 800m = + 5.0moa = -one graduation on the cooper!
800m -> 900m = + 6.0moa = -one graduation on the cooper!
900m -> 1000m = +7.0moa = -one graduation on the cooper!
