Yes, but the time required for these [ISIA speed test] courses are extremely lenient.
Are they? It's 12.5% of the average time of two FIS 50 points course runners (opening and closing runs), and 17.5% for women (
source). I objectively don't know what that means practically (I remember that the openers are WC level, but I may be wrong). In any case, I have never heard of the Speed test being "extremely lenient." More like "that (non ex-racer) person has been training and crashing for four years and never passed." If it were extremely lenient, I don't think anybody would care much about it, as far as being a barrier to getting the ISIA card.
