"I think I just cracked the code on evolutionary items"

#PokemonGO: To keep things short, I want to report the following:I have only received four evolutionary items: a metal coat about 3 weeks ago (7th day streak), one sun stone and one king's rock (same day, back-to-back stops), and one dragon scale. Here's the cool part: sun stone, king's rock and dragon scale were acquired from different stops AT THE EXACT SAME TIME.http://ift.tt/2n2XGvy images are of the last three items I received, the sun stone and king's rock were on saturday, while the dragon scale was today. The curious thing is, I received these items at the exact same time: 4:50 pm, which is extremely bizarre.This leads me to believe that evolutionary items are set to specific times during the day, and that's the reason most people here haven't gotten a single evolutionary item.If I remember correctly, there was once a post about someone who found up to 7 evolutionary items exactly at 12:00 am, which is similar to what happened to me, but at a different time. Probably different times for different players?I'll keep trying this during the week, to see if similar items are obtained.Edit: I live in Monterrey, Mexico, Central Time Zone, the same one for Mexico City, and San Antonio, Texas via /r/pokemongo http://ift.tt/2mFXgu7
