Sure the packaging on any microwavable food will always tell you cook for 3 1/2 to 4 minutes.  Cook for 4 minutes and 30 seconds.  The times instructed always end in a zero, an even time.

Well ya know, people like food prepared differently, and all microwaves were not created equally.

Sometimes I put food in for 3 minutes, 37 seconds.  Sometimes 2 minutes, 11 seconds.

How do you like that?

This was probably my most pointless post ever.
