The flag marker shows an elevation whether it is higher than the tee or lower.
this is shown with a little green arrow pointing down or up on the flag marker.
If the elevation shows that the hole is 35ft low ( = 11Y) you need to hit 35ft (11Y) less.
Same thing applies for holes that a showing a high elevation.
On holes that have High elevation i generally ad an extra yard for good measure.
This all depends on the distance you are from the pin of course. I am assuming tee shots here.
