You, stubborn boyz, don't get simple thing: bounty is 100% compressed, so you need only -c switch.
For abandoned wallets you 100% need both -u and -c switches.
That's 2x drop.
bloom filter with thousands of addressed also cannot be free. Here you get another ~50% drop.
So, 1 address vs thousands is really around "3X difference".
Ok
We "stubborn boyz" have shown you numbers not expectations.

Thanks.
One more thing, about -b -t -p (to Zielar)
