It looks great. Be sure you have the original copy in your bookmarks or favorites. The one in your signature is a read only.
Now for the numbers. What I'd suggest is to "chase the numbers":
When your cat is consistently in numbers too low to shoot at shot time and in numbers in the 100 range and below during the cycle, you can consider micro dosing. This process should be guided on the forum by experienced members and will require more frequent testing. (If you want help with this, post on the PZI forum)
You may be shooting at times longer than the 12/12 schedule, when the blood glucose levels rise enough to require a small dose of insulin. You will need to pick a number somewhere near the 200 range at which you will plan to shoot, being sure that the number is indeed rising. The dose at these low numbers will vary with each cat and its patterns, so advice should be solicited. But you may be considering doses below .25 and even considering a “drop” of insulin. At this point, U100 needles and the conversion chart may be necessary. (For you, I'd think .5 may work above 200 but your testing will tell you.)
It is important during this period to offer small frequent meals. You may want to experiment with the lowest carb foods to help bring down the numbers, staying away from seafood more than once or twice a week.
Does that make sense? You never shoot earlier than 12/12. You shoot when the number is 200+ past 12/12. So on your spreadsheet, he is at 142 16 hours after the last shot. When he reaches 200, you shoot .5 and then monitor until he reaches 200 again - most likely to be more than 12 hours after that shot.
