Markers are only accurate when timeline is 30fps

I create (and watch) online training courses and most are over Zoom, which runs at 25fps. I make handwritten notes during the class to remind me at what time a new topic starts (say at 35:00 in).

I then import the Zoom recording into Screenflow and create a list of markers so when I'm watching the replays I can easily jump to important topics in a long (2+ hours) class.

The problem is that the markers are only accurate if the document is set to 30fps! If I set the document to 25fps (to match the zoom download), when I create a marker, say, at 10:00, the marker panel says the marker is at 8:20! (You can see this by changing the file to 30fps in settings, and the marker jumps to 8:20.) So it seems to be counting frames instead of SMPTE time?

Unless I change the project to 30fps,  then my handwritten notes and the marker list become really out of sync.

Is there any workaround/fix besides setting the doc to 30fps and seeing lots of repeated frames? (It's bad enough that Zoom skips and repeats frames without adding more).

Thanks.

PS. Would also love to be able to export the markers as a text file. Right now I just make a screenshot and print it, but a text file would be great.
