Winter 18-19
------------
* Timing worked well, maybe with shorter break in the middle
* slow down walk through of losing precision.  Maybe discuss more pressing example, such as salami slicing currency withdrawal, etc.?
* make sure to save a few minutes at the end to summarize takeaways
* liked how the implicit 1 discussion went, people seemed to understand that
* maybe solidify via example why fixed point is bad.  E.g. you would need a 200-bit width to store both 1000...0.1 and 0.00....01.

Spring 18-19
------------
* Timing worked well, ran a tiny bit over with break
* walk of losing precision is still dense, hard to understand the different steps to convert to float.  A smaller example might be nice.

Fall 19-20
----------
* Timing ok, but not enough time to demo equality - keep pushing!  Break on earlier side, but that's ok
* liked bank example and minifloat
