In most real-life cases, at least in mine, you never need to look at
all the matches, only at the first few.

I know it's noticeable, and that directly contradicts your time
estimations, because human eyes cannot notice such short delays.  In
general, anything shorter than 50 ms will look instantaneous to us, at
