this does not return similar enough codes on an arduino uno

I installed this on an Uno, pointed the remote at it, got about 16 lines worth of output for each button press.
The lines look similar, I know the numbers can be off a bit, but almost each time at least one number out of 16 is off by 100 or more, making any comparison later to recognize the button, impossible.
I'm not sure if the code is too slow or if there is another problem due to lack of interrupt handler usage.

I ended up using this library instead which uses ISRs and worked fine on my Uno

This is more an FYI to others if you hit the same problem than me.

The issue names no source file or test. Reproduce the inconsistent 16-line IR output on an Arduino Uno, then compare the sketch's behavior with the linked Arduino-IRremote library; done means identifying a concrete cause and an agreed fix or documenting the limitation.
