Will +/- 5 dpi affect my scans?

[Indy]

For my current set-up my cameras are different distances a way from each other so they have different dpi, usually they are just 10 off (for example 236 dpi and 225 dpi). Will there be a noticeable difference if I just scan tailor the whole batch together setting a dpi of 230? I don't know if it matters but most of my scanning material is rather old, anywhere from the 1950's up, and has a lot of pictures in them.

Any thoughts would be appreciated, I don't know to much about post-processing work.

Should be fine I guess.
