I usually monitor SPY index at the following link:
https://www.dailyfx.com/sp-500
Does this match what you have been cited in your postings?
Or I can convert the number you use by dividing it by 10 and match roughly with SPY EFT?
For me, stock analyses is not rocket science, so rough estimates are fine with me.
Also, I believe stock markets are not linear, so all predictions are just educated guess or wild guess. I agree with you that "market is unpredictable".
