Will combined match results be affected if a shooter's score for entire match is on two tablets?

There are minimal due diligence stats person can do before posting results.

Use Match Progress screeen (either from shooter list of from results) to see if all squad completed. Also note number of edits for each squad at the bottom of that screen and see if there is anything excessive. Tap on squad to jump to the squad scoring screen from there.

Also can ise shooter filtering hints like incomplete, apens, edits2, edits3 etc to review scores. See more info on that in Search and filtering shooters in PractiScore apps
