Lets say that astronauts can take for long periods of time 2 g (I know that they can handle 5 g but only for minutes).
This would still result in 4 months journey (there and back).
Not very impressive.
With current technology you can aim at 2 years.
Travel time from Earth to Mars at 1 g of acceleration is 198288 seconds assuming a distance of 4.827 E7 km from Earth parking orbit to Mars parking orbit and flipping from acceleration to deceleration at midpoint of the journey. 198288/3600=55.08 Hours=2 days, 7 hours, 4 minutes, 48 seconds. Or something close to that I might have goofed something minor in calculating but it is under 3 days no matter how you slice it.
You never get close to 10% of light speed because Mars is way way to close of a target, as you pointed out it takes nearly four months to get going that fast at 1g of acceleration.
