Recently, I beat the game with a guns sharpshooter. I wanted to get as much critical hit chance for my character. He maxed luck at 10, took Finesse, Built to Destroy, and wore Ulysses Duster, First Recon Beret, and Lucky shades, for a total of 28% critical chance hit. He took the light touch perk to get a flat 5% modifier to critical hit chance when wearing light armor. I've been doing some calculations, referring to the critical hit chance on the Fallout wikia for the weapons and there seems to be a marginal increase when taken into consideration factors such as luck, equipment, and perks. For example, one of my endgame weapons was the 12.7mm Smg. At 28% critical hit chance with light touch, my calculated critical hit chance was 7.24%. Yet if I set luck to 6 to qualify for better criticals, and remove the built to destroy perk, I get 6.68%. Now for a weapon with a higher critical hit modifier such as Christine's CoS rifle, I got 75% with all the factors I listed above for the first calcuation and 52.5% for the second factor. Apparently, the difference is much greater for weapons with more than 1% critical hit chance. This I just learned. Sure, luck helped me win big at blackjack until I got banned from every casino, but I can't help but feel if luck is even worth maxing for combat builds focusing on critical hit damage, or if those points could be put to better use elsewhere.
