Yes, silvers decide in their own when they're going to run, especially with buckets. I've put a bunch of mine on vac and they turned into totally different trees. I've watched silvers on buckets shut off when the temp starts to go down even a degree, but those on vac will run hard until they freeze up.
Some days though, the huge silvers on buckets will overflow before you blink. Weird.

2017 - Shurflo 4008 hooked to 42 stingy silver maples and a few Norways. A couple buckets on sugars and Norways. 10 box elders.
2018 - ...a few more taps.
2019 - ...more taps on 3/16 gravity. This spiral is heading downward in a hurry.
