Hey Peter, great quarter, congrats to you and the whole PYR team.

I have a question re: modelling that PYR conducts with clients.

Are you able to reveal whether the modelling is conducted either 1/ purely via 3D computer simulation, 2/ real-world live tests of torches in furnaces, or 3/ a combination of both. Perhaps there's a 4th option I'm not considering.

Also, if you are using computer sims, does PYR themselves ground-up develop any of the benchmarking and performance simulation protocols and software either alone or in tangent with a software provider, or are you using a specific off-the-shelf sim tool? Would you see PYR having in-house software expertise at some point if you don't have it now?

All the best and thank you for your time.

Steve
