I think the tolerance is not at all important, compared to the
inaccuracy of the OM-10 shutter speeds.... but I really have no idea
what timing circuit is inside. It won't be a high precision quartz
oscillator, I think.
Since a double resistance value is needed for the next exposure time,
I guess 1, 5 or 10% tolerance cannot have much influence on the end
result.
Anyway, if you want to use one single resistor for each shutter spead,
I think you will be forced to use the 1% tolerance series (E22 ? I
don't remember the number) of metal resistors, or better.... not that
expensive, though ;-)
