A question about Jump Holes

[Xenosaga]

^ Power trading.

I have a pile of XX commodity to be sold at XX system. I jump back and forth jump holes until I luck out and get to the system I want instantly.
Power trading like a boss.

Hardly viable, given the fact:

- The probability of being sent somewhere else is 5% as suggested
- You have to wait 30 seconds to jump again
- You have more than 100 systems out of which you must hit the right one
