@Tracy DeMiroz I generally prefer having the BG reading, insulin, and food information entered as a single data unit.  Often I'll test my BG 10-15 minutes before eating.
 
Like you suggested, I could adjust dates/times later but then ... what's the point of Glooko if I'm manually entering information?  I test my BG 5-6 times a day.  I really don't want to spend any more time scrolling and adjust 5-6 separate entries.
 
Any chance that I'll see charting added soon?  For me, that's the real value of downloading the data.  I know some people export the CSV into Excel and then chart there but ... I already spend so much of my time testing, injecting, carb counting I really want to spend less time thinking about diabetes.
