How do you know that? You can't say that!!!
You just said that some conditions which make the slides inoperable or operate incorrectly are undetectable:
"Faulty Geometric Strap CAN'T BE DETECTED upon inspection!"
"None of the other airlines would detect a faulty geometric strap either!"
"The faulty strap is undetectable upon inspection."
Therefore, it is quite possible that some or ALL of Baltia's current slides are faulty - you can't tell by looking at them - you don't know if they'll work until you attempt to deploy them.
I would think the FAA should require another full mini, and if ANY of the slides fail to deploy or deploy incorrectly, Baltia's certification should be denied. Boy...I wonder what that would do to the pps...
