3~4 seconds using phone's stop watch
I'd say 3 sec dead but no option,
sometimes a whisper over but I'm including a slight delay
for ramp up time before actually beginning the draw
so yeah 3.5s but really the actual draw is likely 3s imho
but kinda how long is piece of string as I have a slightly airy draw
(kinda relaxed chilled draw than an aggressive hoover like draw)
where as a golf ball through a hose pipe is likely going to be a little longer perhaps
(unless you are on ultra high nic & buzzing like fuck with multiple long mad draws)
Many factors involved, but guess around the 3 sec mark looks popular to most
