RE: [WP34s] Regularized incomplete Beta function
Is it worthwhile using CNVG? 03 which will choose 1e-24 or 1e-32 for the convergence criteria (this command is more conservative in XROM than in user code)? This will mean an additional iteration but will give better result in DP mode. I'd probably also increase the iteration limit to 6 or 7 to avoid the error case.

I don't see why it would be worthwhile given the fast convergence of Halley's method. We'd only be getting at most a couple of extra digits in DP mode.
