In the case of 055, I expect the lead ship 101 to undergo something similar to 052D and 172, where 101 will likely be commissioned relatively "quickly" to learn procedures and debug, while later ships are commissioned slightly slower.
However, neither 052D and 055 are following the build a pair and trial/test doctrine of 052B, 051C, 052C, 054 etc as a number of 052Ds were already confirmed to be built well before the lead 052D entered service, and we have confirmed six 055s under various stages of fitting out, launch, construction, before the lead 055 has entered service.
Putting it another way, 052D and 055 (and other more recent classes like 056) are in quite a different category to ships that you mentioned in #5283. Back then it was build a pair, rapidly iterate and advance, and then build another pair. Now they've reached a point where they are likely confident enough in their industrial capability and the capability of their weapons systems to be willing to build a large number of ships before the first ship has been commissioned, or even before the first ship has been launched.
