When I started this post I had just assisted in running my first Pinewood Derby. Now I am the Pinewood Derby Chair for our Pack and am looking at making baby steps to improving our Pinewood Derby Program. We are running a Pinewood Derby fundraiser to raise funds to buy a new four-lane track, but in the meantime I must get by with our two lane track. So my first step is to identify an improved scheduling method that supports our current two lane track and will support the four lane track once purchased. My preference is to use a method from within GPRM to simplify the entire process.
I have been following this post
as theDoc's needs seem to be similar to our packs. However, after getting to a point that seemed like resolution Stan ran the simulators and noted that "Both of these methods require more heats than you may have time for." So now I am seeking suggestions for our Pack.
My parameters are - two lane track, have a timer interfaced with GPRM, each car races in each lane at least once, would like each car to race at least 4 to 6 times. I anticipate approximately 40 participants. I would run as one group with a possibility at setting up subgroups for each Den. (I need to send the top four from the Pack to District, and will award them trophies, but I am contemplating awarding each Den a 1st, 2nd, 3rd place ribbon). I do not necessarily need a Trophy round, though I am not adverse to one. Time is somewhat of a constraint. I'm not sure the Pack will want to change the scheduling method if I suggest it will take longer than four hours.
The recommendation seems to be PPN. I believe a schedule that satisfies Perfect-N or CPN (or Double Round Robin as this is a two lane track) would take too long to run. Phased-Shifted Lane Rotation also sounds like it would satisfy our needs. Dynamic Scheduling seems to have some good pluses, but it seems most are not fans of this method.
So does a PPN, 3 round chart sound like the best fit for our Pack? Or a Phase Shifted Lane Rotation? What are the differences, pro's, con's. Any other suggestions?
It's kinda odd - PN and CPN sound great - but are really not practical for more than 8 participants.
