Something like that, It's odd that people can barely survive a third atmospheric pressure but 71 Atmospheres is just fine as long as the hydrogen/oxygen mix is correct and the subject/victim is properly acclimatised.
I was shocked actually when I read about Hydra 10 when I saw the pressure was over 7 Mega Pascals, considering that venus is average 9.2 Mega Pascals, I'm assuming that it's likely the extra 20 atmospheres might be survivable.
A hard suit might actually be less safe than constant immersion at extreme pressure, I think it might be safe to keep a Venusian colony at perhaps a third of surface pressure, any less would require much stronger containment against the enviroment.
I know this is a significant derail now from the op, but I might as well finish what I've learned about the definition of 'habitable'.
Of course the most habitable part of Venus is actually around 50-65 km in the atmosphere, where Breathable air becomes a significant lifting gas, however if the floating balloon colony was placed at somewhat higher pressure the colony could be placed lower where the atmosphere is actually within tolerable human temperature limits, while at 50-65 kilometers the air would be below freezing.
Another interesting thing is that while Venus's atmosphere is 96% co2 and a mere 3.5% nitrogen, because there is so much gas there is easily enough nitrogen and oxygen there to allow terraforming Venus itself, Mercury, Mars, Ganymede, Titan, Callisto, Io, The Moon, and Europa to 1 ATM of 78% Nitrogen 21% oxygen, of course the bodies smaller than Mars would lose atmosphere rather fast, especially if they had no active magnetic core, and the Jovian and Saturnian moons would need that shield to avoid the harsh radiation of their parent.
But, if ridiculous quantities of energy and economic power was available to terraform the solar system, than theres no shortage of potential "habitable" planets. Bringing this rant back to it's beginning to close I'll just state that it's probably impossible that we'll find an actual habitable planet by the definition of being earth-life enough to support life on the surface without any life support, but we can always adapt either ourselves or the planet to suit our purpose.
Edit: More of a derail, iI was wondering what the cost would be of shifting atmospheric gas by cannon. A babylon gun was assumed to be able to move 1 kg for 600 dollars, which eqates to $600,000 per ton, shifting 20% of the 400 ppm CO2 from earths atmosphere to bring us below 1970 levels would require moving 600 Gigatonnes and cost, 600,000 trillion dollars. I imagine we could freeze it into 1 meter cubes weighing 1.5 tons and just blast it into space. A misfire would probably sufficate a small town if the projectile landed within it. Just a thought.
Oh and terraforming an entire planet would only require 12,500 times as much gas to be moved, and cost a mere: 4,500,000,000,000,000,000,000 US dollars.(if we were firing our own atmosphere for some reason)
