For example, NCC 1709 is listed at 70% complete. Let's say that NCC 1709 came into port with a repair list of 10 items. As of the time of the above screen cap, 7 of the 10 items on that list have been completed. So, the list is % COMPLETE of the requested repairs.
But that still doesn't answer the question why
Commodore Stone is pulling section 18 from the (unfinished) repair work on the Intrepid
and diverts it to work on the Enterprise
Section 18 may be a specialized repair unit to finish the remaining 13% repairs on the Enterprise
but wouldn't they have work sheets and plans for that in the 23rd Century?
Stone is a former Starship commander and now he has to move the repair crews to their next assignment because without his order, they'd just be sitting around?
Whatever the % COMPLETE means, it will mean the same thing for every ship on that list. Otherwise, the graphic is pointless and would actually cause confusion to the reader.
Finally something we can all agree on, right?
