I think I'm still in a honeymoon period where my new (to role playing) players haven't started doing that yet. thankfully.
Which reminds me to ask, has anyone done anything similar for MgT2 trade? that would speed things up considerably. I'd be happy with MgT1 or Cepheus Engine as they're close enough for my purposes.
The bit with working out what spec cargo is available and what price it is is the tedious bit. I'd do it with a spreadsheet if I knew how to get it to look up a column with trade classifications and so on. my Excelfu is not so much a 'fu as a Excel 0, 'can make it do basics'.
But yes, I can see the fun of Jumping around known worlds buying and selling a la Elite in a rather more speedy fashion than my hand rolling and calculations. my brother's bought the new/current version of that and raves about it. l I'd join him but I'm doing so much sleeping of late I don't know when I'd fit it in... <sigh>.
Tomorrow... ship combat! there must be a pirate lurking at the bottom of the Aramis Trace! Six Jumps so far with an encounter roll on the way in and on the way out (I.e. 12 rolls) and not one roll of 6 to generate an encounter! (2 out of 9 deaths in the low berths on that last Jump though. Doc was having a bad day).
