China Visa Application Questions # 2.5, and # 2.6

Hello, Application question #2.5 asks for longest intended stay among all entries. Do I SPELL OUT the number of days or, is using a NUMERICAL number acceptable?
Question #2.6 asks for itinerary in time sequence. Do I list ARRIVAL DATES and DEPARTURE DATES for each city or, just ARRIVAL DATES?
Thank you very much.

PS - If I appear hyper cautious its because I am. The nearest consulate for me is 125-miles away, and I have read some postings where if you forget to dot an "i" or, cross a "t", applications get rejected. (Figuratively not literally). ... Thanks again.
