Im actualy pretty lucky lately with getting silvers from 2k summon. Out of last 5 days i got silvers from free daily summon in 3 days. Just got Nenya today (who i actualy didnt manage to lay may hands upon until now - not that i need her but hey)
Ahahahaha.
I knew I'd have to change my answer not long after making this topic.
Got my first plat from SP summon.
I spent 100 crystal fragments I got from the subjugation and stampcard; didn't get a single silver. Only iron and bronze.
I got a gold from 2000g summon once though; I think it was archer Stray.
