Not better, worse, because prediction starting at year 2280 cannot be falsified until then.
Again, what does your Model predict for the next few ENSO cycles? Identify the shorter and longer periods. Then today's geophysical community will see just how valid your Model is in the most fundamental parameter of period prediction.
The Hypercomplex Multi-Chaos Geophysics prediction is that a purely Tidal-forcing ENSO Model will be unable to make sound specific predictions of individual cycle periods, because it neglects applicable physics.
