Meiwa kumquat and new Zealand lemonade.

Not a mandarin, but my fukushu kumquat, flowered twice-ish this spring (bloomed, set fruit, two weeks later set two more flowers and those became fruits, and then a month after that went through another bloom cycle and loaded itself with fruit). About a week ago it set another bloom, that's now a little fruit that has started to grow, and the bottom half of the tree is now blooming.

Congrats guys, what a nice surprise!
