I assume you trust logic and empirical tests. Here's something that is both repeatable, and as empirical as it gets. Consider every instance of knowing anything "objectively". You will notice that consistently it is always first and foremost a subjective experience. You can't get around it. Thought is very quick to dissect, categorise, extrapolate etc. and then you create a division of the thinker, which you take to be yourself, and the things "out there" which are separate from you. You take your understanding of the world as absolute truth, while spiritual giants, dared to dig much deeper in a manner no less scientific than the greatest scientists the west has known, only directed it inwards instead of outwards and arrived at understandings which are no less remarkable than what scientists have. The difference is that they can't demonstrate it by getting a rover to mars, but by becoming totally free of any form of suffering caused by an incorrect understanding of reality, which I dare say is at least as impressive.
They say they're free from suffering, maybe they are, maybe they aren't, but they can't tell me how to repeat that in a way I can reproduce for myself. Which is my entire point. Maybe something worked for them, but won't work for me or vice versa.
Results that can't be replicated and aren't predictive aren't really results at all. Not in a logical or meaningful way. They're just claims. Bizarre and baseless claims.

If that were true, I'd take the same position as you do, but the good ones never tell you to trust them. In fact they insist that you look for yourself with brutal honesty and never trust any guru on their word. In fact, I see their conduct as the epitome of the scientific method, only directed at understanding what's at the core of the subjective experience. What experiments have you tried so far to claim that these are bizarre and baseless claims?
Source? I cannot name a time when it has produced meaningful and repeatable results. Therefore I'd say it's illogical.
