How Much Does A Google Properties Stack Boost An IFTTT Syndication Network?

In the 129th episode of Semantic Mastery’s weekly Hump Day Hangouts, one participant asked how much a Google properties stack boosts an IFTTT syndication network?

The exact question was:

After an IFTTT stack is in place, how much does a Google properties stack (interlinking google docs etc.) boost the network and what tier should they point at and how soon can/should it be plugged in?
