The Jaguar is rated as follows:
-40a continuous
-60a for up to 2s
-100a for up to 0.2s

At 60a, the 40a snap action MX5 will trip between 3.9 and 47 seconds.

According to the Jaguar's spec, it has exceeded its spec limit before the best-case breaker trip.

So maybe we shouldn't use Jaguars, because we can pull more current with a CIM than they are rated for before the breaker will trip?

The point is that, in our use-case, it is reasonable to exceed the continuous current ratings for a short period of time. The Spike also has the highest relative current rating of any FRC-legal controller.
