Proper baseboard Sizing

My 1950 (levitt) slab house. ranch. With origonal radiant heat (starting to leak in spots) is on its way out. And i am planning a full baseboard conversion. 3/4 pex for the whole job and slant fin 30 baseboards.

I ran the numbers through the slant fin program to calclate baseboard size. and i am wondering if this sounds right

The house is a 2x4 construction with fiberglass batt insulation, slab with carpet, and tile in bath and kitchen. The room dimensions are as follows and the size baseboard slant fin came up with. Are the program numbers accurate? the house has new vinyl with 1/2 plywood and 1/2 foam over tyvek. new roof and new double pane replacement windows.

Office 12x18 with 20' exterior walls. 2 24x44 windows = 9' fin line 30
bedroom 12x12 with 12' exterior walls 2 35x50 windows =12' fin line 30
bath 5x8 with 5' exterior one 44x24 window = 3' fin line 30
kitchen 11x13 13' exterior Bay window 48hx80= 6' fin line 30
living room 22x17 sliding door 34' exterior 18' fin line 30
master bed 14x17 21' exterior 2 26x40 windows 17' fin line 30 (this room is under unheated space (attic)
hall 8x4 witha 32" door 3' fin line 30

some people have told me to follow these numbers and some people have told me to just loop the whole exterior walls of the house with fin line 15

this will be pushed off of a well Mcclain wbv 03 110 w with a riello head

the first floor will be 2 zones, one for the master bed room one for teh rest of the hosue.

the second floor already has baseboard
