I'm having a couple of issues with TransX. I've been using the tutorial by Capt. Crybaby and following it to the letter. I've done this trip 5 times thus far and have the same problems.
1) MJD: I claculate my launch window and write it down, then set Pe, save the scenario and advance the date. starting 24 hours from launch, I do my alignment, which I can get down to an Rinc of 0.000### at which point the number starts fluctuating and I can't get any lower (I figure that an alignment within the 10,000th of a degree range is good enough). The problem is that according to the tutorial, I should reach the MJD that I wrote down 30 seconds from my Pe. Every time I have done this (and as I said, I'm following the tutorial to the letter) the MJD and my Pe have been off by several MINUTES! This last flight, the MJD was off by HALF AN ORBIT (and no, I didn't accidentally flip my Pe and my Ap)!!
2) Cl APP: While calculating my launch window I tend to calculate it to impact (I figure that this will be easier to correct than only getting my cl app within 20k km). By the time I actually LAUNCH, the cl app has drifted out to between 5 and 8 MILLION km. WTF?
