Sizing gas supply for dual fuel range

[bigb56]

I am installing a new dual fuel range. The burners are as follows: LF=21,000
LR=12,000
RF=15,000
RR=5,000
CTR R=9,500
CTR F=9,500
TOTAL=72,000
(Oven is electric)
The line is 3/4" tapped into a 1" 20 feet away. The 3/4" tees to 1/2" for the range and 1/2" for the clothes dryer, back to back. I want to use a 1/2" supply line 48" long to the new range. The manufacturer says I can use 1/2", 5/8" or 3/4". Question, given my BTUs will I gain anything by changing the tee and upping the supply to the range to 5/8"?

PS: I cannot envision a circumstance where we would actually be using all size burners at once, let alone at full on.

Will you gain anything? You'll gain btu's. Do you need them? I doubt it.

I think I'll stick with what's there then and see how it goes. Thanks
