I had a brief look at the tides and spokes. My impression was that it was well presented. I am curious on the large expressions for which you used subexpression elimination and wonder if you have tried `lambdify(..., cse=True)` on them with any favorable results. I look forward to spending som

Hi Chris, thanks for the kind words. I haven't tried the cse=True approach in SymPy, I'll check it out when 1.9 comes out. I would imagine that the outcome will be similar to the CSE in our expression system, but it will be interesting to know if there's something new we can learn. Kind regards,
