For context, see the following market, henceforth called the Main Market:

When looking at the market after its resolution, what will I think is the amount of steps Manifolders needed to get the correct answer right with >90% probability?

Details

Note that this is not quite the same when the Main Market first hits 10% or 90%, in that short spikes, market manipulations etc. do not count for the resolution.

If the Main Market visits >90% but later marketers become uncertain and the probability comes down, this will not count for "getting the correct answer right with >90% probability".

As I'm not particularly interested in precisely specifying what counts for market manipulation and don't want to encourage edge case attacks, I will leave the description in its above vague form. This market will resolve according to my subjective judgment.

I won't trade on this market (nor the Main Market) and will not attempt to manipulate it unfairly. I comply with reasonable requests to slow down the pace of new information on the Main Market.
