Why are my crossovers different


So the schematic on my m1 crossovers says that c2 circuit (midrange circuit) should total 26.7uF
The crossover that I just recapped had the c2 circuit at 25.7uF.
The crossover I’m working on right now has the c2 circcuit at 28.1.
It does not appear these have not been tampered with since the factory.
So the question is should I make the second c2 circuit match the 25.7 of the first or should I put it back the way it was at 28.1

I could make the second one a 26. 8uF. I accidentally damaged a 1.3uF that was in the 28.1. So I’m debating on whether I should replace it or leave it out.

Your input would be appreciated

Maybe the caps the factory used ware not accurately labelled. Question is, how accurate are the labels on the jantzen standard z caps 
It's strange  because on the first crossover there is a 10uF, another 10uF, a 4.7uF and a 1uF, making 25.7

The second crossover it had a 10uF another 10uF, a 6.8uF and a 1uF making 27.8
These are only what is printed on the caps. 
Again the schematic calls for 26.7
 
I'm thinking they likely measured each cap to make the 26.7
Also on the 25.7 crossover the 1uF cap it said 1.0m100v,  I assumed this meant 1uF.
 On the other crossover the 1uF cap had the stripes, I punched in the stripe code online and it said it was 1.3uF-1.6uF at 100v

Why not get a meter and measure the actual value of caps from both crossover and go from there?
