Hmm.
I just checked it against LBB7 Merchant Prince. The same table is on page 37 of that book. The tables are very similar, but there are differences.
LBB7 has Wa sourced goods getting bonuses when selling at In, Ri, and other Wa worlds.
There's also a column for Wa in LBB7, giving a bonus on Wa worlds for In and other Wa worlds.
Looks like they tried to clean up and reformat the table, but some things got lost in the shuffle. Note that T5 p 491, on the VA column, has In in the column otherwise holding De codes.
I suspect this is indeed a point of errata, but I don't know what the "right" values should be.
I'll wait for a couple more comments, and then add it to the Errata thread.
Thanks for the idea!
