Troubleshooting EIGRP Route Advertisement

I don’t think this statement is true or at least its not in the perspective i am thinking about it:

“Lesson learned: When you redistribute something into EIGRP you need to configure seed metrics.”

I injected a static route into EIGRP in production and it worked and I did not add any metrics at all.

I basically have talked about it before but I just added a route-map and used a match statement and it showed up in EIGRP on the other router and everything worked great. Before I tried it on production I built a GNS3 lab and tested it.

So am I not understanding correctly what that statemen5t means which is possible I am a bit crazy I am told.
