Okay first show season. Depends on how they're being promoted first with either commercial or high fashion aim. Also depends on if they're first priority is money or prestige. Also brand new girls tend to come in "packages" in their first seasons in which case an agency might propose one girl on the terms that another gets picked as well and vice versa.
In otherwords, a majority of one of those girls shows could have just been booked not because of her demand but because she came along in a package with another girl who clients wanted to book. It's a possibility, but it works regardless. There's no better or worse.
In your example, the model who did 10 shows skipped London and Milan. That's typically skipped when a girl is put on hold for an exclusive. Looks like the pattern that happens with Prada "holds" which most new faces get put on hold for anyway. If she didn't get an exclusive I'd say she had a rough start with only those 10. Some good shows but it's not much exposure. The one who did 15 was notable in Milan and will have more exposure but missed New York which a lot of people inside the industry ask about. Both I'd say didn't have the best first season :-/
