Knowing the specific time of each drop makes dropcatching more effective, especially if you're going after a batch of pending delete domains. It doesn't help for names that are heavily targeted by backorder services. However if you are only competing against others using registrar api calls you will achieve better efficiency by only sending api calls for 1 domain at a time. So for example, if you have a list of 10 domains you want to catch, you would normally just start cycling through each domain at once when the droptime begins. You are wasting precious resources and time by blindly trying each one. Now say you know the order of the drop and approximate time each will drop. You will only be targeting 1 domain at any given time until it is registered and then rest until the next domain drop time approaches, so on and so forth. Hope this helps.
