I agree with Cobgoblincave4 that we are hitting a bit of a bump in the road with the accuracy figures for XRP; currently sitting at 75.54% when forecasting price volatility. I am confident though that we will get it up into the 90's like many of the other tokens we cover.
Latest forecast and historical for XRP below as an example.
So how do you improve the accuracy? Do you feed new data or is there any tweak to the algorithm? I believe some coins are just wildly volatile since their fundamental changes quickly like XRP after the SEC case, so it is not surprising if your current model failed to stay within 90% like other coins. People should be aware that this 'prediction' can't correctly express any change in fundamental values if I get your explanation correctly.
