Yes, I agree !
When you’re nearly in tune the tuner is nearly useless, because the gap is too small graphically but still huge to be tuned I think !
Strobe tuner make it easy to see and easy to be accurate because it’s not a graphical precision, but a motion that guides the tuning : less it moves more you’re reaching the “perfect” tuning.
If making a strobe tuner is too time-consuming a log scale would be a more precise choice :
..|----------|----------|----------||----------|----------|----------|
-100>>>>>-30>>>>>-10>>>>>>0<<<<<<+10<<<<+30<<<<+100
