I think most people would agree with Stuart and others who are on the side of the argument that says a matchday increase in ticket prices definitely puts off walks ons as coupled with other factors such as family/work schedule you’re less likely to go out of your way to attend if you feel the club is unnecessarily charging more because you can’t/don’t know if you can attend for whatever reason until the day of the game itself. It’s like with train companies increasing ticket prices on the day compared to advance fares which in effect penalises people that have fluid schedules/circumstances in day-to-day life and puts them off travelling by train and ends up alienating customers meaning the train companies don’t make as much money in the long term compared to a few extra higher fares in the short term and leaves people dissatisfied with the train company as an organisation.
The only vague ideas of ticket sales comes in the form of articles/data like the one below from both individual clubs and the EFL and other instances of club/league officials replying to fan questions at forum meetings etc.
Obviously articles like this will only paint rosy pictures whilst marginalising any negative instances of ticket sales/attendances as they are trying to promote brand awareness/sell their product.
Following that logic, clubs and the league aren’t actively going to put out statistics that show how pricing structures they put in place to make more money in areas wherever they can without being called out on it by the majority of the fan/consumer base negatively affect attendances etc. as they’d be shooting themselves in the foot.
Until the fans forum asks the club to supply the data (which I imagine they’ll do begrudgingly and take as much time as they can over) you’ll have to rely on the opinions of other fans (both on here and in the real world) that in my experience has always pointed to a matchday increase putting people off.
