NavList:

Brad,

you asked "do we fill in these characters, based upon known computation to fit or do we leave them illegible" concerning the noon latitude calculation on April 26th. If you can't find any traces of numbers that agree, I think you shall leave it as it is. But make a note about it. We cannot exclude the possibility of a mistake from Worsley's side.

Now I think we can explain every single figure in the log to make sense, except three minor issues:

29th April, bottom left, there is a transformation from time 3^h22^m6^s to arc 50°31'34" that correctly should be 50°31'30". Either you have misread, or Worsley perhaps looked at the line for 7^s instead of 6^s if he used some table for the conversion.

7th May, top left at the pm observation, there is a lonely "30" (above 5.10.14) that I cannot explain. And on the same day we have the observed noon longitude given as 39°3'6 which I would rather read 39°34'.
