OOPS I had overlooked this. Thanks for the comment - I'll have another look at the long version, and I'll try to understand the reason for removing more than only the silly part. For now I only had a quick look at it, but my impression was similar to yours, it sounded plausible indeed. I did not check it carefully as, IMO, GRT remains Einstein's theory even if someone else would have published the most axact equation before him. There is more to it than the 1915 equation.
