Yes, they are. My C does the same. Ultimately over the week, if you count down from 105 to 0 you are pretty much achieving the same as using 15 a day, its just a bit more of a grey area in terms of encouraging a "binge" which could get out of control.
Personally, I save my hexs and syns for after WI, come home, have my tea, and then have a couple of hi-fi with a hot chocolate for supper. Makes me feel like I have had naughty stuff without blowing it.
