Generally no I don't blind call except in the rut. If I get bored I'll pull out the doe bleat and give a few soft calls from time to time.
I think an old buck would be more likely to swing down wind during an all out grunting/bleating/ratling sequence than if you just give a few soft calls. I think if a buck swung downwind of every deer vocalization he heard, he'd never get where he was going.
