Rosette number in manes? Odd/even? Does it matter?

I've always learnt that you should plait odd number of rosettes in mane (+ forelock = even), well it's not something that I've had to do but I'm OCD so I always have stuck to that as my own rule (also heard that you should traditionally plait on the right side but I was just taught to plait the way the mane falls). I recently found out that it used to be traditional for geldings to have an odd amount in their mane (which means it's been OK cause I have a gelding) and that it's traditional for mares to have an even number in the mane (+ forelock). Does it even matter anymore? Does anyone stick by this anymore? Is it something that judges even look at? I've been doing hacking for some time (I'm the only enthusiest at my stables), I've been a ring steward/marshall, get paid to groom and to plait but it's something I've never really noticed.
