So to be secure, [* 0.8]  (1/1.25) will prevent such clips I guess.
As the series being somewhat are, perhaps for wavetable synthesis, I 
guess a larger factor or a simple [clip] may be practical as well.
Anyway I appreciate you backing me up with my question.

It was a rough guess taken from my understanding of what the formula 
did, however, I had no idea "why".

The whole idea of polynomial interpolation to me, was something I had to 
read multiple explanations before understanding. Yours certainly carried 
me through the last few steps to reach my goal.

Thank you so much.
