I just accidentally shot a roll of Kodak E100 at f/11 and it should’ve been f/8, per my measurement.

Do I ask the lab to push or pull the development 1 stop?

Push one stop. Slide film does not have much exposure latitude. On the other hand modern negative film, color or black& white, has a lot of exposure latitude.

Depends on the light. If it was very flat light, you could consider asking for a one stop push. If it was contrasty light, I'd have them process normally.

I bounced a strobe light off of my white ceiling and measured f8

How high is the ceiling and what was your working distance?
All asked in order to have a sense of how diffused the light would be once it got to the subject.
And what is the nature of the subject - persons, jewelry, Christmas cake, ???

Push development is an attempt to correct the lack of exposure, as in your example.

When calculating the aperture from the Guide Number, one must use the distance from the camera to the ceiling bounce point plus the distance from the ceiling bounce point to the subject, not the distance from the camera to the subject.
