Yes, we are almost nitpicking here. The real problem is what I hinted at. The volume of change per difference on the dipstick is completely unknown. A quarter inch on the dipstick could be a pint, or two ounces, or a quart.
The fluid in a transmission is not a large top surface area, which would give a predictable change when adding fluid. The actual surface is broken by the valve body, and shift brackets, servos, etc. My point is that the actual space that the fluid can rise is probably like the surface area of a small bowl, or large glass. And it is different at every different level.
Sometimes adding trans fluid(say a pint at a time) will raise the level only 1/8". The next time it might change by 1/4", or 1/2". I have seen it go up by close to an inch, when adding only a pint. I usually add no more than a pint at a time, rechecking after settling.
Thus the amount that this trans we are talking about is over, could be as little as a few ounces. But not knowing the actual volume for that amount of dipstick distance, we are guessing that it may be more than a pint, getting to a worrysome amount.
I'd try to pull a good pint or so out, and recheck it. Good luck,
