Southwest Rapid Rewards - Boarding Priorities for non-A list, non BS passengers

Most of the posts here recently have been about the successes that A-list members and those paying BS fares have had. I am not on the A-list and do not pay BS fares. I fly Southwest about 5-6 times a year and therefore will not likely ever be in either category.

I am therefore wondering what boarding priority people have gotten who are in my position - not A list and not paying BS fares. Thanks.

On 2 recent flights, I did OLCI at 24 hours prior to flight time, and I got A21 and A19.
