My 25C and 29C are not as different as those you show, perhaps because they are both Continuous RAM designs as you suggest.

Overall I do see LED brightness variation among the ~10 Woodstocks I have, and I assume that this is just component variation and/or battery strength, and not indication that any of them have problems.

I've found that when treated properly (i.e. charging batteries outside the unit, not dropping, etc.) Woodstocks are fairly resilient and reliable.

I've done the same comparison and I agree with Bob, I mean I think the difference is due to the component variation and/or battery strength, (swapping or interchanging the batteries, between different calculators makes the difference). I've compared even two not continuous equal model feeded with the same battery pack and the difference is appreciable
