Thinking about active insulin

On the Minimed 530 G, if I go to Basal Review, Standard Basal (11.35 u total), it looks like this:

1)00:00  0.850 U/H

2)05:30  0.200 U/H

3)14:30  0.450 U/H

4)20:00 0.600  U/H

If I pretend that Regular (which is the insulin that I pump) is equally active in the hour that I get it and the subsequent three hours, then the amount of basal insulin lowering my blood sugar in each hour is:

0000-0100) 0.6625

0100-0200) 0.7250

0200-0300) 0.7875

0300-0400) 0.8500

0400-0500) 0.8500

0500-0600) 0.7688

0600-0700) 0.6063

0700-0800) 0.4438

0800-0900) 0.2813

0900-1000) 0.2000

1000-1100) 0.2000

1100-1200) 0.2000

1200-1300) 0.2000

1300-1400) 0.2000

1400-1500) 0.2313

1500-1600) 0.2938

1600-1700) 0.2563

1700-1800) 0.4188

1800-1900) 0.4500

1900-2000) 0.4500

2000-2100) 0.4875

2100-2200) 0.5250

2200-2300) 0.5625

2300-0000) 0.6000

Which looks much more like a smooth rise from 2 in the afternoon until three in the morning, and a drop from five in the morning until about nine in the morning.
