Belle Boyd never got much air time at all on Nick GaS. It took Nick GaS like a year before they aired that episode again. The whole episode is enjoyable though. But you're right, if the episode got more air time, it might actually get discussion than it got in the past. Luckily, more people recognize Belle Boyd for featuring a great team that got shafted by a brutal layout. Even though Matthew and Leah took a longer path than usual.
Actually, none of the bottom of the central shaft runs were played that much either IIRC.

I mean Queen Boadicea and Priceless Portrait were not played very much because they were like the last 20 episodes I needed to see. But it looks like our list is very similar for those temple runs.

I didn't include Electrified Key, Golden Ship, etc. because they don't really compare to those four.
