i agree smaller is better.
how about the following?

commit b4a624761fe90aa0d57264013287f4236077ac9c

ofproto.at: Fix races in rule eviciton tests
Bump timeout differences, because timeouts different by 1s might end up
to have the same position in the heap as rule_eviction_priority() uses
1024ms as a unit.
Also, use time/stop to avoid relying on how long an add-flow would take.
These tests were introduced by commit 6d56c1f1.
("ofproto: Update rule's priority in eviction group.")
