Does Stored Power's base stat increase if a stat is lowered and then rises?

So, say I had a Sigilyph, and its defense was lowered by one stage, and then increased back to normal, that is a stat boost, but does does Stored Power’s base power go up?

Stored powers base power depends on the number of positive stat boost youhave. So raising a lowered stat will not increase it’s base power. And the maximum base power of stored power is 860. We can see that this is not factored by a raise from a negative stat change.

Hope I helped:)Source

The move Stored Power’s base damage isincreased by 20 times the total sum of the user’s positive stat stages: that is, its initial base damage is 20, but if one of the user’s stat stages is 3 and another is 1, its base damage will be 20 + 20*4 = 100. -Source

So it wont lose any BP when it goes Sigilyph gets a negative stat change, but it also wont get a increase in BP when it gets back to normal. It doesnt have any positive stat changes yet, because the positive change was canceled out by the negative. Stored Power will still have a BP of 20 until that Sigilyph has +1 Defense and not neutral.
