This doesn't tell you much. As noted the lift angle is set incorrectly, and should be 49 degrees. This means the balance amplitude you see is overstated by about 18 degrees, so the 254 is actually more like 236. The beat error is too large, and the rate in this one position looks okay.
But none of this is worth anything unless you know what the state of wind in the movement is. Next what is the variation in positions? Unless you keep the watch in this position all day long, this tells you absolutely nothing about what the timekeeping performance will be when the watch in the wrist.
Sellers tend to add these things in for proof of something - most of the time it proves they don't know how to use a timing machine properly, and not much else.
