Annual Cycle of Growth

I have been keeping a chart of our vineyard's annual cycle of growth since 2015. I read about it in Ed Hellman's online publication called Grapevine Structure and Function.¹ It is a good primer that I refer to time and again.
I took his annual cycle of growth chart and modified it so that I could include information on all of the years that we have had a harvest so that the information could be seen at one glance.
This is what it looks like with this year's information filled in so far.

What charting our annual cycle of growth does for us is to give us some guidelines as to when major events of the developing grape vine will occur. Right now, we are on track for harvesting our Auxerrois first and then our Chardonnay. Unless our Chenin Blanc catches up in the next few weeks, it looks like we may be harvesting our reds before our Chenin Blanc.
If you are interested in keeping your own log, here is a template:
