The math is actually quite simple to do yourself, your dilation factor is just 1 / sqrt(1-x^2), where x is a percentage of c from 0 to 1. So at 0c, your factor is 1 (obviously), at .5c it's 1.15, and at .9c it's 2.294.

Divide the elapsed time in the stationary reference frame by the dilation factor and you get values that roughly agree with yours.

Of course at 0.9c, the non dilated travel time is 22 years, brought down to less than 10 years due to time dilation.

oh, yes of course, going faster you would obviously arrive earlier even in earth frame of reference :)
