A reasonable person would not see 70% growth as impressive? What level of growth is the cut off point for impressive then? Or for reasonable people? This is the problem. You keep trying to spin it as if only your way is reasonable. As if it can't be thought of as impressive unless it has impossible levels of data presented with it.
You don't think 85% of customers engaging with a secondary service as impressive? When you also think that most people don't think the service has much benefit? It is telling that instead of answering the questions you instead are repeating yourself with an explanation that isn't relevant to the question answered. We have enough data to label it as impressive. We don't have enough data to know how many of those 175 users were active the entire year. That is irrelevant to the 70% growth year over year statistic though. You even present an extreme scenario that you don't think applies as a way to discredit Amazon's statement. Yet you have no bias? Lmao.
