I also observed this and decided to use one scale. That caused larger errors 
for very small I. But the non-exponentiality (I hope it will be confirmed
by others before we definitely accept it as a fact) is much stronger than
what can be attributed to random reading errors. And I have many points.
Next time I plan to use a digital voltmeter and measure I*R over the 
resistor through which the capacitor is charged and discharged.

I hope you saw my recognition of the graphical integration error discovered 
by John. The Internet is so slow; the messages I posted last night did not 
bounced to me yet.
