It depends what you've got and how far you are in the game. If you are finding yourself having to send ordinary trains in order to send Richard something - then yes you are correct.

However, if you already have these (which I have as on Level 771), then it's easy. Notice the above table shows how the XP rewards go up and up (which moves you forward in the game). I've looked. Currently sending Richard Contract 42 - plastic. I can see that when I reach Contract 50 for Richard, then I will probably need a break from him in order to boost supplies.
