Darren's database is an amazing resource, but I actually use this list more. I keep a copy of it in the "Notes" field on my phone. I find it to be the easiest way to reference the details on certain patterns. Especially in those critical moments when you need to make a quick decision on something for sale in the exchange. I should add that I find both the original list of half stops and the full list in post #3 of lengths, etc. to both be really helpful as a quick reference. Thank you for keeping them updated!
