I add the caveat that my suggested values are tentative
That should be fine. I usually ignore estimates of piece values anyway, because I don't expect them to be gospel truth, and when playing a game, I rely more on my own ability to understand and compare different pieces. But piece values could be of more interest to someone who is trying to get a program to play a game better. As someone who is programming engines to play Chess variants well, it makes sense that HG would have a keen interest in this. I recall when Steve Evans and I were working on a better Shogi ZRF together, and one thing we did, which I think was more his idea than mine, was to add code to adjust the values Zillions-of-Games assigned to different pieces.
