Sorry for the late Response, i havent seen your posts until now. I can see where you want to go and will try to back my assumptions with some numbers. This is Warcraftlogs, probably not your prefered method of evaluating numbers, but for me it is. I would also like to play around with the Simcraft Algorithm but i have not found the time to do so yet.I know as a fact that "the person" does not.But the person who wrote the algorithm most likely uses it during openings now.By the way, Simcraft doesn't WJ during opening.
Judging from the number of people who aren't entirely convinced by you, I'd say there is quite a lot of doubt. It's fine to say that you have no doubt, but to convince others you need to bring up some solid evidence, instead of just saying "it is better". Just as you can name a lot of reasons why it might be better (ie. 2 FoF guaranteed for PC,), many others have named reasons why it might not be better (FO's first FoF munched, forced Icicle dump if you IL before PC, losing PC/FO uptime). The discussion is a stalemate until either side can provide supporting numbers.There is no doubt that WJ before PC is a dps increase. Having 2 extra lances for PC is such a BIG dps increase that its out of discussion. Aswell as the fact that those frostbolts trigger your passive Trinkets.

Those are the first 6 Entries of mythic Kargath Frost Mage (except 5 with is Russian and i cant Read . They all use WJ at the very Start. Most of them use the FoF Proc's before FO+PC to avoid Munching. While you should not put all weight on Warcraftlogs as those minor changes to Openings have little impact to the overall dps, you should atleast ask, why didnt mages placed Top who didnt open with Waterjet.
I have checked a few more mages and found 1 in the top 10 who didnt WJ at the start (first WJ at 17 sec), he is currently placed 8 (Flêks).
The general idea of those mages is:
Use FB+ WJ at the start
Use 2 Ice lance
Use Frozen Orb
Use PC
Iam actually not entirely convinced by this either. Using both Ice Lances before PC decreases the Risk of munching FoF Procs, but might leave you with very little procs during PC. Interesting options would be to just use 1 FoF Proc before FO+PC or cast FO during PC.
We will probably never be able to define the ideal way, as we are dealing with Procs.
