Apart from your example I tried the following variants of the same equation. While some of them are working, I was able to generate a bunch of other bad results:

Yes, I went down that path as well. The real problem (for this example) is the value of R (and as Tugdual points out) also the use of variables. The EQN system has some issues, and as we'll see in bug # 15 (coming later) some of that can cause data loss if you're not aware.
