Yes. Because they often have a playfield design that bottlenecks gameplay (upper playfied of WWF) or a fatal software bug.

There is one danger here with WPPR5.0. The data tracking commitment. This is what doomed PARS even though it was a mathematically fair system. It was difficult to keep track of individual match outcomes. Rather than just providing who won and lost, the tournament director needed to also provide the win-loss record. Furthermore, it was tedious to enter all of these win-loss results even when they were provided since there were so many to enter into the system. The end result was a system which failed because of the large queue of unentered results and the large number of situations where win-loss records either were unknown or too exhausting to obtain by continuous requests for this information from each and every tournament director who failed to provide this information.

Enter the original WPPR system: easy to implement and the tournament director just needed to provide the finishing position of each player. Kaboom!! Pinball is now running on all cylinders because of this genius system, tournaments are everywhere and it is now starting to cascade into increasing pinball locations in most large metro areas. But now the pendulum swings toward an attribute (data minutia) which has been incontrovertibly demonstrated historically by PARS not to work as described above. I just hope this does not undo all the IFPA's hard and magnificent work.

I totally get that it is desirable to reduce backyard tournament point inflation and increase accuracy. So I guess there has been a shift in philosophy towards accuracy, rather than the original primary goal of increasing the popularity of competitive pinball which the earlier system addressed perfectly. Time will tell if this adjustment gives the worst of both worlds since tournament directors might just submit results the way they always submit them and get the low point treatment of the new system even though the tournament might have a lot of great players involved, thereby not only impeding popularity but also accuracy.

As a comparison to having to now keep track of # of games played and time spent from beginning to end. I'm just saying that the more metrics (individual records was the stat drag in PARS), the less likely you will be to get accurate submissions (which is the whole point of WPPR5.0).

Great, so I guess we'll be seeing a resurgence of PARS.
Regardless, having to keep track of individual records (versus just whether a player advanced) doesn't change regardless of the interface; and it was a big factor.

I'm hoping the new system is a big success. It's got some big shoes to fill, made by its predecessor.
