Thanks for sharing your thought about strength calculations in Bazi-Calculator.
I totally agree. The use of the Strength chart in Bazi plays a very minor part.
For beginners, it is an easy sell as a visual way to read a chart.
Yes, I really think strength chart is a minor part.
However, I can assure you nothing in my calculator was designed to be a quick sell. Rather, it was designer as a tool that would be useful for myself and my friends initially, later shared with the public.
Elements calculations method are not my invention. Depeding on option, they come from this or another modern master. Most stuff connected with traditional BaZi are I think from Ken Lai school. While I have his agreement to use his techniques, I don't have his permission to share them (sorry).
So, the charts are a quick glance for me, but they are not taken "from hat".

I was initially introduced to Bazi as a way to understand the five element balance within a person, not to read the chart.
We used the five elements to help understand how to balance a person's life via Qigong and other methods.
We also do this in Chinese Medicine.
I totally agree, this is how I currently use them. I think they can be useful in TCM.
So, I like having the calculated strength information. And Yes I only used the natal chart info.
Yes, the
Natal chart elemental info is quite straightforward.
If we come to "date to compare" chart, thing get really complicated.
This is because it all depends on what purpose we want to use this information for.
To see current year energy? Or current date? Or current year with LP?
To see energy levels during a specific time (for TCM or QiGong)? Or to compare the energy to day master strength chart?
There are completely different uses.
In fact, one would need to project different chart for different uses.
But still, these charts are trying to put metaphysics in numbers, which is quite bold, maybe arrogant idea, from the very start!

Its interesting to note, when looking from a traditional Bazi reference, one thinks about the strong / weak - favorable / unfavorable groupings. From a five element reference we look at the Shang / Ke cycle primarily (especially the Ke cycle).
Thanks, it's valuable. This is one more thing I don't take into account.
So many factors. That one would be used for the purpose of energy levels (TCM) rather then DM strength comparison (current design is leaning towards the latter).
Voytek, I am glad you mentioned that your calculation add the LP and Xing Nian, as I don't think I would want those influences added into my view.
Sure, for some purposes, it would be good to see energy levels without it. But to some other purposes... isn't LP most important influence?

Isn't AP important? Isn't LP important? Isn't current season important? How to count all that?

Let's end with the conclusion, that there are many factors, some of them I didn't think about, thanks for mentioning those.
The algorhytm is not my invention. I know that it's not perfect and is not taking many considerations into account.
Some time ago I thought of testing it on thousands of charts somehow and perfecting it. But recently I am more into MangPai, so I don't feel like directing my time energy in this direction.
Generally the above charts are designed mostly for DM strength calculation, work best for Natal chart, as for Date to compare, they are including all pillars with LP, are not including interactions and 5 element cycles.
Creating perfect charts would be a task for ...months or even years of design and testing! And would need to include different charts used for different purposes.
