and the Germans still paid more then they would with a more generous early bailout because they had to repeat the process
A more generous early bailout would have meant that the Greeks spent it even faster.
That would actually be the point.
Look at this from an engineering point of view. The problem is Greece has debts it can't pay off. The reason it can't pay it off is the economy is too damn small, not growing fast enough, and lenders are convinced they won;t be paid back if they send in more checks. If you have a mini €110 Billion bailout (at 5.5% interest) then the Greek government has to fire slightly fewer people then if there were no bailout, but it can't create business tax incentives/build infrastructure/buy domestically produced tanks/or any of the other things governments can do to make the economic pie actually grow. None of the problem has been solved and you'll just have to spend €150 Billion (at 3.5%, except the €100 Billion write-down in debt from the last bailout) more next year.
Which will still not be enough to allow the Greek government to spend new money on shit that might grow the economy, so a few years after that you have to deal with Syriza. Which means that a) you have not solved the problem, b) you're not getting paid back on the €260 Billion you gave them, €160 Billion at 3.5% and c) you're really truly not getting paid back on the €100 Billion gift.
OTOH, let's say you started at €200 Billion. You didn't charge interest, or you charge 1%. Maybe you're feeling really generous payments don't start until there are signs of growth. You insist the Greeks make major changes to their economy (for example, reducing pensions and replacing their easily bribable tax enforcement guys with real tax enforcement guys). They use the extra money to grow their economy. Which, BTW, is logically equivalent to saying "they spent the money."
Now you have solved the original problem, you are getting paid back on all of it, and nobody has to worry about the end of the Euro. You have not caused a banking collapse in Cyprus, you do not have to deal with Syriza, there is a 0% chance Putin can turn your entire left flank simply by courting the Turks and telling the Greeks "you realize if you just stopped paying those guys I'd protect you, right?," etc. etc. etc.
