I'd like to ask a few questions concerning buildings:
Concerning the CK City Map & Building Database google docs:
https://docs.google.com/spreadsheets/d/1ln1LSQwPajGNMhtQ8LieWKyQ4rgo-Vnr6-NHkx-Ee00

how relevant is it? If it and game info disagree game supersedes? (like when the offered 1 xmr noobshacks are show as 24 sqm in map, 7sqm in game)
google docs says max building height in borough 4 is 15m, there are houses for sale with 16m.

Another question:
There are plots with buildings for sale in b4 and b9 for max. 2xmr. Any Opinions which would be the better buy? B4 buildings offer better payouts but they are 3 floor buildings in a doomswamp.
good, noob friendly OTC offers welcome
