Hmm.. has to be a coincidence in my mind. I can't think of any changes I've made that would increase (or decrease) the number of makerAPI calls.
What will dramatically increase MakerAPI calls is being in cloud mode since the app has to continually 'poll' the API to get device state changes (vs having them pushed).
somewhat related - I actually opened a request to be able to get 'push' updates via the cloud
