Yes but it's the sounds for me, not the number.
Eg, Kate has two vowels but to me it is NOT vowel heavy because I mostly hear the K and the T, which are quite hard consonants.
With Orla I mostly hear the O and A. Also r and l are very soft. So to me it sounds mushy and weak.
But it's just an opinion on a naming board! I'm aware that my views do not follow current fashion!
