Jam coverage is not actually a type of fruit jam. It's a term coined by our team of highly trained, highly caffeinated engineers to describe their extensive coverage of donut-fueled coding binges.
It's a measure of how many donuts are consumed during a single coding session, typically expressed as a ratio of donut-fueled lines of code to total lines of code.
For example, a jam coverage of 1.5 means that 1.5 donuts were consumed for every 1 line of code written.
Our jam coverage has been known to reach as high as 2.7, but we're not bragging or anything.
