All delists use "actuals" which are released a day or 2 later.
The purpose of the adjust is to instantly bring the price in line with the expected 4 week total, rather than let it happen gradually through market forces.
There are 2 halt prices. The Friday halt for MOVIE.OW is frozen at 10AM PST and would be a good way to see the market estimate prior to tickets being sold. Just multiply by the proper factor (2.7 for a normal 3 day weekend) and you get the HSX community's estimate. A year ago, this WAS the halt.
On the other hand, the Saturday halt has let market forces move the price after Friday and early Saturday ticket sales are known. Generally, the prices will move closer to the actual delist price, as data has started to come in to help with projections. (In NFL terms, it is like trying to reset the line after the first half. )
To be honest, I know that the purpose of HSX was to sell data as a predictive tool and with the current 2 halt model, I am not sure which data gets sold, or is considered the most important measurement of potential box office sales. Remember, basically, this is a giant opinion survey disguised as a game.
Good luck in your research.
