Hi Rick,

'Morris' out of 'Morris, White and Crowther' here.

Great post and great job on the plots – thanks! I stumbled across it while revising the draft paper and your comments are really helpful.

Here are a couple of notes from me:
1. I googled 'zipper' and discovered that it is American for 'zip'. So while the term would bring clarity for Americans, it would alienate other English speakers, so I plan to stick with zip (having rarely/never seen people plot zero-inflated poisson models).
2. My graphs use the same fractional ranks as yours – I didn't bin the centiles (zoom in really tight on the pdf).
3. This really works! I suppose people can make sensible decisions about what proportion they want but I really like how your graphs focus in on the action, and I am going to include a comment about this in the revision.

All the best, Tim
