Wow! Way to go Casey!
Maybe then hold it for now as you are getting lower numbers in the middle of the cycle. Those purples could be a bounce since the blues were lower than she's used to. If you got blues, then I would probably stay with the 1.50...at least now until this bounce clears.
Any chance you can get the 1/2 unit markings? My vet gave me the 1 unit markings one and I still have 3/4 of the box of those. I got the 1/2 unit markings and Im using those now, figuring that I can just use the other ones when I'm back to a whole number. Just thinking of what would be easier for you. I was eyeballing it at the beginning when I started the 1.5, and its a lot easier with the mark right there. Especially if you're going to be going up or down 0.25 in the future. Up to you!
Loving the blues!
