Yes, I was actually pleased to see that in terms of price drop, we really only 'lost' about one year to the big crash. It could have been much worse.

Price drops on ball python morphs aren't ALWAYS predictable, but they do follow some trends.
In general, co-dominant morphs drop faster than recessive morphs.
'Popular' morphs will drop faster than less trendy ones, though less popular morphs may not be very high to start with.
(This is why spiders have come down so much).

Popular recessive morphs hold their value extremely well. In spite of being among the very first morphs discovered, look how long it's taken albinos to come down...and then look at where piebalds are STILL...it's impressive.
