Since the bounty will close soon I just noticed that the allocation of PTT's computation is wrong.
As per OP
Bounty pool allocation = 75,000 PTTs
Participants:
Bitcoin Talk signature campaign 40% bounty pool
Twitter campaign 30% bounty pool
LinkedIn campaign 30% bounty pool
OP computed as follows
Bitcoin Talk Signatures Campaign (40%): 20,000 PPTs
Twitter campaign (30%): 15,000 PPTs
LinkedIn campaign (30%): 15,000 PPTs
It's only 50,000 PTTs but they indicated a total PPT allocated 75,000
Check here:
https://bitcointalk.org/index.php?topic=5100378.msg49352184#msg49352184Allocation should be:
Signatures Campaign (40%): 30,000 PTTs
Twitter campaign (30%): 22,500 PPTs
LinkedIn campaign (30%): 22,500 PPTs
A total of 75,000 PPT.
