I enhanced my build time spreadsheet to calculate the number of log entries for all the categories and the total.  It's interesting to see how many hours per work session I've averaged (about 1.8 hrs).

I must say I love my setup for the spreadsheet.  It's a Google spreadsheet, so I have the Google Sheets app on my phone in which I enter my work session right there in the garage.  Then it automagically appears on this blog.
