What Ma Ge said was true. There were a variety of space allocations that even Kraft joined in the selection process and gave his opinion based on what he knew via a quick System search. In the meantime, Xiong Da was there looking at them and seeing if Ma Ge and the others were going to throw some other stunt.
If they were able to attempt to 'cheat' the Panda Clan, all the more they should be careful when they sign the contract for the land acquisition. After all, when someone felt like they had won, they would most likely be in 1the most vulnerable state as well.
That and it was Xiong Da's fault that he did not see this coming. He had never expected one of the Royal Horse Clan's family members to be in direct contact with Jin. And the line where he said the 'Pandas' acumen' was bothering him. There were no cat or bear like families in the Royal Zodiac and the closest was the Tigers.
