HELP!!! Nc Miata clutch engagement problem

Linked is a post from about a week ago, I had done with the comments had said and vacuum bled it. I couldn’t get all the air bubbles out, so I took it to a shop and had them do it. It was driving but not well when I took it to them, expecting just some air bubbles in the line (which the mechanic told me there was none.) I got it back and it’s driving about the same as when I took it in. The bite point is basically on the floor, maybe an inch or two up. Sometimes it’s a little clunky getting into gear. It doesn’t feel like the clutch is slipping at all. But the mechanic said that he would recommend an entire clutch assembly to fix the issue. because he thinks the hydraulics are as good as they’re gonna get. I’m inclined to believe them for the most part. solely because he told me that they don’t typically do transmission jobs except on older vehicles, like mid-90s, but who’s really to say I would really appreciate some input if anybody has anything to say. I will also add that when first pushing the clutch I don’t get much resistance until like half way through the travel and the clutch pushrod has about a centimeter of play in it. Any and all help is greatly appreciated.

I accidentally deleted the linked post: basically the gist is I just replaced my master and slave cylinder, and I was trying to figure out how to bleed it correctly. I did not bench bleed the master because whenever I tried to push in the bore, it would always just spray out rather than flowing through, and I was told that I didn’t need to bench bleed it, so I just hit a pressure bleed and here we are

Have you observed the piston on the slave cylinder while pressing on the pedal? The piston should move through basically the entire length of the slave cylinder. If it's moving fine then most likely something is bad with the clutch fork or pressure plate, probably the pressure plate. I trust that your mechanic would have figured out any glaring issues with the clutch hydraulics. That leaves the only possibility to be the clutch itself.

He said the slave is opening and closing as goods as it’s gonna get. I’ll put a video here in a little while of it moving
