How to fill this unforgiving oven timer with 60 seconds run

When this timer counts down a timing-in-progress, pressing the up arrow will not add a full 60 seconds. Instead you get a refund on the expired portion of the current minute. Depending on minute freshness, an up arrow could buy you a few seconds or almost a minute. With a little patience and quick reflexes, you can extend a timing-in-progress by just over 60 seconds. Wait for the minute to flip, and press the up arrow twice as quickly as you are able. Now you will have 60 seconds + lag between the minute flip and your successful double up arrow press.
