It's gratifying to hear about your seeming success at achieving what you had hoped to.
The suggestion of the use of Poly with SS that I made some months back on the SS thread was based on what it obviously brought to the RS_MaxxMud I was using at the time. I had followed and contributed to BCortez's thread since it's inception, and a overriding complaint buried among all the exclamatory posted evaluations by the "KISS" crowd was that it was just too dark. But a little later, as PB_Maxx looked to the efforts of Mission's work and experimented with the use of a Top Coat of MW/BF, it became quite obvious that the MW/Poly could and would ramp up SS's abilities to please a larger, more critical crowd.
PS_Maxx's ratios had to be both heavier as far as the Poly, and lighter as far as the BF mix because the BF at full strength is far darker than SS. That, plus his emphasis for a while has been to make the BF mix more applicable to lower lumen PJs.
For a lighter Grey hue such as you used as a Base coat, and your 2K Lumen output, you made the right choice. Anyway, the point is that recommendations we/I make along these lines are not guesswork, they get posted AFTER they have been proven viable. They are not to be considered the absolute last word, but they should not either be dismissed or dissed by a few at the expense of everyone else.
As I said at the start, I'm glad you decided to give the Poly a whirl. What works for one Grey based application can and probably does for another if it's done correctly. and the variables you tried have help narrow down the range of experimentation to a definite recommendation for others. THAT is what DIY "sharing" is about. Providing knowledge and help via actual examples to those who need/request it, through posts/PMs/or personal interaction. Those who only complain or discredit can't really offer anything but the same.
It's all the better anyway when someone attempts the detailed trials that you did instead of just blindly going with a suggestion, because if one does have the time and can spend the effort required, then they have all the better grasp of why they reached the point they did, and express the reasons much better for others to learn from.
In the excitement of bringing such 'proven' ideas to the many who cannot/will not make the effort you did, it is required that you express yourself in superlatives if:
1. You really believe in what your posting.
2. You want to prompt a "fence Sitter" into action.
But some will read into that an attempt to place your suggestions above all others, especially if you both get a lot of responses, and continue to express the same viewpoint in your many subsequent posted replies. It's a "no Win" if a few want to take issue with you for "being there" all the time.
Sometime ago, when this this Forum was part of "Screens", it was filled with people asking questions about DIY, but very few screens were being made beyond BO cloth and White Paint (...excepting Goo screens which at the time was the only quality DIY app around.) A main emphasis was made by a few during the SM/MM craziness for people to "Just Do It" as far as making their various attempts, and all in all, that's what happened.
Nowadays, there are many more choices. Examples such as yours help 2 ways. Some will read your results, dispense with any "experimentation" and go straight to getting with it. Others will use your example and get the "Virus" and start doing their own testing.
In the end, it is always best for the actual "Do'ers" to make the effort to validate claims made by others, no matter how incredible the screenies. When that happens, usually all the 'questions' and recriminations (...if any...) against a particular application will stop. Usually.
I'm sorry if it seems that I helped spin the other "SS as a Base" thread out of control, but when I see things posted, and directions being taken that have never proved out to being worth doing after "hundreds" of previous posts and attempts, it does seem pertinent to let people know. In actuality, doing such can save many a lot of grief and wasted effort. Had it been BCortez, T_Minton, or even yourself, no doubt the response would not have been "Stop Promoting". Alan wrote to me to say that I should just let others find their own way through the "Learning Curve" but that is very hard to do when over the last few years I have seen so many posts lamenting failed efforts and the time/expense that was wasted.
The real issue is for people to keep open their minds to both new ideas and existing proven applications as well. We can all benefit if everyone works as a Community, instead of factional Groups. Courtesy toward each other is something that makes it all seem fun and worthwhile, and those who do not practice such are not doing anybody any good, but themselves.
If this post seems that I'm singing your praises, while lamenting the lack of other's efforts, I am. Despite what went on "over there" on the other thread, you kept up the spirit of your intentions to find a solution, and did it in a through and evenhanded manner.
A good job excellently done. Congragulations.
