Flaw with example from TechnicalSummary

[psyantyst]

There seems to be a flaw with the example at the end of the TechnicalSummary document:

From Figure 2 it appears that the last 5 users will lose more reputation in voting (even when fully in line with the DC) than they will gain by the time the last user votes. Since they will never be able to regain the cost for voting, it's rational to say that they wouldn't vote. Knowing this, user 5 would also not vote, as he too will be unable to regain the cost of voting if no other user votes after him. The same reasoning extends all the way to user 1, and therefore it is not rational that any of them votes.

Is this an issue with the parameter setup of that example, or a general flaw of the voting process?
