How to read the Temp basal delta value from Loopalyzer Nightscout report?

[janvitos]

I've not seen this mentioned anywhere in the Nightscout documentation, and I didn't know where else to ask, so I decided to ask my question here.

I am trying to figure out how much more basal insulin the loop is giving my son at different times of the day by analyzing the Temp basal delta values from the Loopalyzer Nightscout report.

My son's regular basal is 0.5 U/h. His Temp basal delta is often 0.5. How do I use the 0.5 in relation with the 0.5 U/h? Do I simply do 0.5 * 1.5 = 0.75, which would equal to a delta of 0.25? If not, what's the proper math here?

Thanks!
