But for um the average person that wasn't so well known at the time we were doing this and it was a bit of a surprise to see that a lot of people some were did have very good glucose control but some pre-diabetics were what we call moderate spikers. we came up with named glucotypes as it's a way of quantifying this and uh and then some people are spiking just as bad as diabetics and had no idea uh and so it's a way of revealing what was going on.
