Only if you learned every one of your routes from different neighbor.
If you have two exits and 100000 routes, you calculate twice and
apply the results to the prefixes.
Note that this does not apply to a proprietary, "hybrid", semi-link
state protocol marketed with name "EIGRP" where all routes need
per-prefix calculation. (OSPF and IS-IS work fine)
