SEO Strategy and Reporting frequency

I have a client who is in the strategy execution niche. we've been doing SEO for 3 months now and we started off with monthly reporting and as our relationship became more focused on results he is having me track keyword rankings, backlinks, and all other metrics weekly so we can monitor results vs efforts so he can know when we should change strategies. We are tracking 50 keywords that we are targeting and i tried to explain to him that there will be times of large ups and downs when algorithms update and that it is wise to wait for the dust to settle before changing anything. He insists that we should be able to monitor weekly and adjust each week to gain optimal results and growth. How can I explain to him in the most simple but advanced way that SEO doesn't occur and results do not take effect that quickly? We are targeting highly competitive keywords within the Philippines. How can I show value after 3 months to keep him onboard. We are starting to rank for keywords and have trackable data (position 100 or better) with 11/50 keywords starting to rank. 4 of those phrases are top 10.
