What do you guys consider to be 'high enough' level to get to the point where you can max out the tournament rewards? Obviously it would depend on how much you want to babysit the clicking aspect, but a ballpark figure should be close enough. It's not so easy to extrapolate from any particular point with the logarithmic cost progression.

My assumptions about tournaments:
1. For income generation, nothing matters but seat 11. Not even golden/mega golden time on other seats makes much of an impact.
2. In furtherance of point 1, shares spent on employee multipliers go only to those three that affect the employee you always assign to seat 11.
3. The other seats make up the bulk of the levels (duh).
4. Temptation to spend income on seats 1-10 should be resisted until near the end of the tournament in order to maximize total income from seat 11.
5. Ideally, since their income doesn't matter, use 'max level' purchase on seats 1-10 only one time right before tournament end to skip purchasing their upgrades. (Obviously this point becomes moot once you're high enough.)
6. Boosters and time skips help tremendously, especially when combined.

Are any of my assumptions incorrect? Did I miss anything important?
