Not including zero on Y axis is misleading, especially with bar charts.

Not in this case since he’s just interested in how much the time changes not how fast he solves it.

Yeah the differences are so small that if the y axis started at 0 all the details on the graph would become too small to see.

Relative magnitude of the change is important. If time changes from 10 seconds to 10.1 seconds, it's not the same as time changing from 10 seconds to 20 seconds. If you don't include zero, you can scale the graphs to look the same.
