Edge keys seem to miss keys more often then central keys
When typing I tend to have to re-press edge buttons (or so it appeared) every so often. So I did a simple/crude test of repeating a key quickly 3 times, then doing a separate key 3 times. I did this on Chestnut and Birch seems similar results.
The most accurate reproduction steps I could find was comparing two inner keys like
h where I would get 100% tap to character occurring to the farthest keys
0 where it would miss some sometimes.
I did this by opening up 'Text Editor' and repeating as shown below.
