night and day and trouble free 9+ yrs now

I see yor logic also,the BR is bypassed while cranking so its getting the full 12 volts...but mine was still sluggish and had to crank over1-2 times before liting off and running

same with the 85 truck after a intake a carb swap and the points dist droped in fires right up instant..would crank over 2-3 full turnes then fire off and run

I reachin and hit the key its running like RR said..before the key snaps back

I havent really looked any further as it works for me
