qa ratio

how high can u take qa ratios bg good till lunch normally taking a 1.5 1 the last 2days i have increased it to 2-1 still getting high bgs can increase it again

Take whatever ratio needed john m. But make changes as part of a controlled long-term evolution based upon your findings over the weeks and months to come.
My lunch ratio is currently 2.5:1 and I report it as 2.5. On this basis, your ratios for Friday would be 2, 0.5 and 1.
Your text implies that you are using 1.5:1 for lunch which would normally be reported as 1.5 but has been reported as 0.5-1.
We need to get in as much information as possible entered correctly. The database you are creating, does lots of clever stuff in the background, which you will become familiar with.
