Well, Wikisteff, on Twitter, with the "25th order Runge-kutta integrator in Excel without using VB" (To be honest I don't really know what that is ;-/) test file responded to the thank you with;
"I, for one, cannot wait for more multicore/GPU. Libre is a fantastic product, and I would be happy to share my sheets, such as they are, with them."
So, question for the list; Take him up on the offer?
If there is a use for another test file I'll let them know and IDK get it to the QA group, I guess - ?
Thanks

Howdy,Thought I'd pass on a twitter exchange, to the list here, between myself and Wikisteff regarding another attempt to benchmark some of the changes to Calc recently.
Wikisteff: "Oh, yeah!
I wrote a 25th order Runge-Kutta integrator in Excel without using VB as well."
Wikisteff: "Well, it *was* part of a head-to-head test to see how GPU parallel evaluation of floating-point code worked in practice on
@LibreOffice Calc.
@MSExcel was the control. ;)"
Me: "I would love to see results from a GPU parallel evaluation of floating-point code comparison between Calc and Excel. Is that available somewhere? thanks."
Wikisteff: "I didn't publish my results, but they amounted to "if the calculation is simple, like a uniform linear transformation or a matrix multiplication, high speedup. If the calculation is nonroutine, like a nonlinear transform interwoven with large matrix products, no speedup."
Anyway, I haven't replied on twitter yet, will in a minute or two and thank him for his time and that piece of feedback.
Personally I don't know if any of that is useful as feedback, hope so.
Best wishes,
Drew
