63 ppm of sodium diluted as prescribed at 3oz/qt. in your EcoBoost is about 5.9ppm additional for a full sump. Hardly anything to write home about.
As far as the calcium, maybe one of the tribologists can comment if there are different calcium’s that do not react for LSPI, or if the phosphorus/ester/moly types can offset calcium. While I like seeing proof, if Lubegard said unsolicited that it is designed to combat LSPI, based on their track record with other additives I’m inclined to believe them. I did ask several followups of Lubegard so we’ll see what they say.
