Dear hartreefoch,
Thanks for your quick reply and references. I like to follow the "Trust but Verify" adage when it comes to measurements.
I'm finding it difficult to accept your assertion that this exercise is just an illusion. A simple party trick may be easy to pull at a children's gathering, but not to a group of adults. Also, it would be somewhat unethical and legally risky to sell if there were overtly false claims. I've checked the archives and cannot find any comments/complaints about this. So I'm giving the benefit of doubt and assume that I am either doing something wrong or my finger joints are somehow non-standard, if that's possible.
It doesn't matter to me whether I can grow my fingers or not, as I didn't buy the course for that reason. I view this exercise as a proof-of-concept for SFQ. But since I can't get past this step, I am now unsure about making further progress. Perhaps there are other exercises which could substitute for this one.
Cheers.
