Range Calculator status report

I am continuing work on this calculator. There appears to be some holes in the NEC application rules for Table 220.55. For instance, what do we do with ranges, cooktops, and ovens when they are supplied by the same feeder or service and they vary in values from about 3 KW to 27 KW of unequal ratings? This project is attempting to find the feeder or service load for up to 1000 ranges, ovens, and cooktops including any combination of these for ratings of 1 3/4 KW to 27 KW allowing up to 10 unequal ratings. The input is by mouse selections using 0.1 increment values for KW. A separate calculator is being created for branch circuits.
