What about construction, scams, hacks, pk's, deaths to NPC's, glitches, trips to Karajma, low-alchemy, drop parties, lost/dropped, lumbridge/al-kharid gates, quest items from NPC's, buying strength potions, selling stuff cheaper than it normally is (face it...inflation/deflation play a big part of this. If I sell rune plate for 75k, and Oziach sells it for 84k, thats 84k not getting drained...) We can also never forget what happens when we invest in rares. _________________ Construction equations: 4 Bil. gp Daily. Around 800k planks are made DAILY. That's 800,000 * 600 (average spent on planks) * 7 = 3.3bil + Servant uses: 4500 * 9 *3600 *15 / 7 (averagely 7 uses for servant before payday) = 0.312Bil + other costs = ~ 0.6Bil = 4.212Bil gp PKing doesn't loose money. It just falls into somebody else's pocket.
