Can you please help me answer these questions as Google has asked me the same. I had requested higher API limits for our accounts. Currently I am chewing threw them .. probably at some rate of around 30000 accounts for 150k API Calls.. have gone through 3 accounts already and have managed just to push out 70-80k object changes
The number of users. - About 300,000
Average number of requests per day/per user (calculation describing your expected usage of the API).
Which API methods will be called and what will be the frequency?Are you polling the API changes to user resources?
