Chen shi taijiquan developed from Chen family style, tongbei, Shaolin, etc of the day along with synthesis from close family members so inclined to martial endeavours!
I would say that it is always ongoing as eveidenced by the laojia/xinjia dajia, etc variations that evolved according to the historical period!
I have no idea ho wlong it would take to finalize but a teacher of mine one toldd me that in his wushu class from a traditional teacher (1950's mainland China), he was to choreograph a form based on a well known taiji style. It took about 6 months but again a template was in place on which to copy!
