How do you know how sharp your image is when taking the shot. Unless you are tethering (or wireless) to a larger viewing device (such as a computer) it's difficult to know. I can press the zoom button on my D800e up to 11 times to zoom in but it doesn't indicate what percentage zoom I'm seeing. To solve this I filled the frame with a 12" ruler. I then noted what was viewed for each of the 11 clicks on the zoom button. Then I viewed the image in Photoshop and adjusted the zoom in Photoshop to achieve what was viewed for each click. Here are my results:
Nikon D800e LCD View%
16% at no zoom
21% at 1 click
26% at 2 clicks
33% at 3 clicks
38% at 4 clicks
50% at 5 clicks
66% at 6 clicks
95% at 7 clicks
160% at 8 clicks
200% at 9 clicks
400% at 10 clicks
600% at 11 clicks
I find this handy, especially for photographing birds in flight or when hand holding with a heavy lens - it may look okay without zooming in on the LCD but I typically want to know what it looks like at 100% and now I know to do 7 clicks on the zoom button.
Different Nikon models and other manufacturers will likely have different results, so you shouldn't use the above without checking.
To OP. Have you plotted this data and tried to fit a curve to it. The data are not linear. At the begining the δχ values are around 5 at the beginning and 200 at the end. Sure would be interesting to know why.

On my D850, I have set the middle button on the up/down/left/right area to automatically zoom in to 100%. This only happens while in Live View. You don't have to keep pressing the + button to zoom.
Start with Custom Setting Menu, Multi selector center button, then Live View, then Zoom On/Off, then you have a choice of Low Magnification (50%), 1:1 (100%), or High Magnification (200%). Press OK when finished. Its much easier to press one button one time rather than 7 times.
Good luck.

This is why the LCD screen is not the greatest for focusing with. Also, there is lag time with the LCD, so if you are trying to follow moving things (especially birds in flight!!!), you'll never know what's happening focus-wise. Better to use the viewfinder.
Even in moderate light the LCD screen is nearly impossible to see much of any detail.
I don’t disagree with any of the comments. This post is for those who zoom in on a photo in camera to see how sharp it is. Here are my thoughts:
1) Although the camera may have achieved focus, as indicated by the green dot, it may not be sharp enough for significant cropping in pp. For me, this occurs mostly when I’m photographing wildlife at different distances - some further away than I would like but due to constraints I cannot get closer. The method I described now allows me to decide whether I have a keeper and whether to keep shooting at that distance.
2) I use live view for subjects that would not be out of my frame or out of focus distance within 1 or 2 seconds. When on a tripod I always use live view for shooting the moon, and other slow moving or stationary subjects, but certainly not for birds in flight.
3) I was in a park provided structure that served as a blind on Wednesday at Cape May Wildlife Preserve and it was very easy to chimp and check on focus. However I didn’t know what any of the zoom clicks meant. This has occurred before and so I finally decided to figure it out.
This is another tool for me and reduces frustration in the field.
Thanks to everyone for viewing and commenting.

Depends - my camera can magnify the centre of the screen (focus assist) and I don't shoot birds. But I use my EVF anyway. IF I did BIF I would have focus tracking switched on.
So while you’re doing all this calculating, your subject flies away?
Kate:
Ha! I guess you haven’t been in the field. I took 280 shots on Wednesday, so no they didn’t get away.
I’ll take take your comment as a quip and nothing really negative.

How many were keepers? Could we see some please?

Lots of duplicates so I always delete about 90%. So, 20+ keepers. I take all in raw & will be culling & processing later. Will post a few in another post.
Thanks

No, your battery dies and the shooting portion of the day is ended ...

I guess one great pic makes it worth it
