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

So going back-to what GS5556 said is it probable that Mirage Deviated from what the schematic said of 26.7 depending on what the drivers read. This would mean that each speakers crossover May have a different value depending on The drivers that it had.So for instance The mid range circuit in one speaker might have a total capacity its of 27.5 and the mid range circuit in a different speaker would have maybe 25 asper how they matched it to the individual drivers in the cabinet 26 being the baseline but the factory would deviate as-needed. is this likely 
I've heard these older pairs were hand built, so I guess it makes sense the midrange  circuit of each speaker could be slightly different from each other. 
Update

So measured the old caps.

In speaker A, the midrange circuit measures 24.7
In speaker B, the midrange circuit measures 26.3
It's a 1.3 uF  difference. 

Speaker A midrange circuit has been replaced with 25.7

Now I'm trying to determine  whether I should put speaker B the same as speaker A (25.7) or back to where it was at (26.3) or 26.7 which is what the schematic calls for. 
Your thoughts 

On speaker B I could use 2, 10uF and a 6.8, or
2, 10uF a 4.7 and a 1.5.

Is there a benefit to using the 4.7 and the 1.5 over using the 6.8
