Inacurate documentation on market-prices

The following average prices diverge:

Commodity	doc	plist
textiles	7.2	71
radioactives	23.2	231
liquor/wines	29.2	291
narcotics	51.0	512
machinery	56.6	560
furs	70.46	704

Moreover "luxuries" with 90.2 is exactly the same value both sides, only it is not the average of:
(78.0+102.0)/2 = 90.0
So I guess it should be one of:

1. 78.4+102.0
2. 78.3+102.1
3. 78.2+102.2
4. 78.1+102.3
5. 78.0+102.4

But so far I haven't worked out where the calculation formula rounds it's interim results. E.g. looking at "narcotics" again, with price_economic = 0.00 and price_random = 1.00 I'd expect a range of
0.0 to 102.4 or
0.0 to 102.0 depending on the correct average, whereas the given values are
0.4 to 101.6 ???

Apologies for taking so long to respond.
The next revision of the OoliteRS.pdf will have updated market information, which will be completely based on observable information in the game (compiled by jumping to every system and compiling the results). The difficulty with the trade-goods.plist info is that weighting and randomisation can skew the results.
