Another SNG Theory Question

[La Brujita]

A Party 100+9 starts with ten players 1000 chips and blinds increasing every ten hands. Now many of us argue what the upper bounds of ROI and ITM are, but many of us have opinions that are pretty close (perhaps 50% ITM and 40% ROI are close to the bounds-ROI I don't know since I don't really track it as closely).

What would the two upper bounds be in the following cases (feel free to answer all or any):

1. Blinds increase every 20 hands

2. You start with 2000 chips

3. Blinds increase every five hands (a bit odd I know)

4. You start with 500 chips

5. Blinds increase every 100 hands

6. You start with 10,000 chips.

I really don't have a great guess as to the answer to these questions. If you desire, please also feel free to guess average time for each (lets say 45 minutes ballpark average for standard). I ask partly out of pure curiousity, partly in response to a recent thread about someone's friend trying to win 1/3 and partly to try and figure out what would be the ideal blind structure to make money on these.
