Pin oak/ slow grower

I have a pin oak that's maybe 25 ft tall. My buddy told me it's a pin oak and I agree.
He's a pretty knowledgeable guy . He was guessing it at about 75 years old? I have read
That the pin oak is a fast grower? This looks like a slow grower to me ? It's a pretty tree
And seems happy and heathy to me. Acorns are on the ground.
I will let it live its life but is this a slow grower or what? The trunk is maybe 5 inches around.

 

The pin oak I planted at my last house grew at least 3 to 5’ per year. It got big fast. Got a pic?

 

Not a pretty shot, I was trying to get you close enough to see the leaves.

 

Are the tips of the leaves round?

 

Iv read that the oak will slow down and mature slower. Are we at the slowing down phase? The land was cleared a few years ago for our new home. This was the only tree I saved on the frontage. It just seemed wrong to take it down.

 

Here are a few

 

It's probably a white oak
They grow slower wood is stronger
Nice trees less messy then red oaks

 

Pin oak limbs grow downward.

 

That’s not a pin oak

 

Really? What is it?
