Sentence 1: yeah what's funny is the idea that uh you know what i consider you know like a three-quarter backswing or even a half backswing uh my friend says that's you know that's a full backswing and you don't want to go any further than that so i mean it's a now it's a matter of trying to convince myself that that's right

Sentence 2: My friend says what I thought was a three-quarter or half backswing is a full backswing and I shouldn't go further than that so I'm trying to tell myself that's right.
Is this second sentence entailed by the first sentence?
yes
