Dragon Ball Z Buu Saga

I may be behind time. But after having some illogical arguments with a friend regarding Buu Saga, I watched DBZ Buu Saga for the 5th time and came up with my ranking of strengths of fighters. All other saga where pretty clear, only Buu Saga is complicated. Here goes my analysis.

1. Kid Buu was always toying with everyone till he saw the spirit bomb.
2. Super Buu was warming up with Gotenks for Gohan.
3. Goku was stronger than Fat Buu fresh out of ball, but he wasn't at the same ease with Kid Buu.
4. When Gotenks timed out inside Buu, Goku told Gohan no need to fuse and turned to base form, means Gohan could fight Buu by himself. That time Buu with Piccolo and 2 Super Saiyan kids should be slightly stronger than Super Buu. This means Gohan might have taken down Super Buu, more easily than Goku or may be Goku couldn't.
5. Buu with Gotenks or Gohan made Goku run for fusion means he had no chance and so was Gohan when Gotenks was absorbed.
6. Going with talks and calculations, this can't be ranked. For example, Goku stating Buu is twice strong as before. But before what. Buu with Gohan or Buu with Gotenks, obviously not. He would not have had an equal fight with Kid Buu at all. He would have ran for fusion again. May be he meant twice stronger than initial Fat Buu he fought earlier.
7. Gohan was not transferred to Supreme Kai planet to fight with Goku and Vegeta. Means Kid Buu can be stronger than Gohan.
8. Buu can sense Gohan's power increasing from Supreme Kai planet but did not cared of Goku there, means Goku's power was way lesser than Gohan.
