A representative number of what? The real price of the CPA? But google controls both the bid price and the ask price, so it could be arbitrary for all i know.
Every other marketing option also is arbitrary. A social influencer doesn't owe you a low price, they will charge what they can. Google will charge what it can for CPA etc.
Once more, there are thousands and thousands of influencers, their price is set through competition. Google is only 1 (one) company, no competition to force them to adjust their prices.
