Hi Jeff,

thank you for reviewing and commenting my stuff!

This will actually execute many queries (1 query for each show, for each network). It's what's called a n+1 query, and a frequent performance problem.

Instead, you could:

Show.where(day_of_week: weekday).eachdo |show|
putsshowend

After all, we don't need to group by the network at all here.

Things look good!
