10 minutes of 60% comprehensible = 600 comprehension-units, and we don’t know if the meaning to language matches are correct or not.

That 1 minute of English is well used, not abused.

And for those who have doubts whether the use of English in TPRS is less than 10%, I have data proving that it is.
