Generating smaller amount of ores?

[Terrails]

I want to generate my platinum ore 1 per chunk, something like emerald but without defined biome generation. I'm not sure how they do it on emerald but I've made my own World Generator and used it on my ores but when I get to a really small vein size and chance it just stops generating the ore. Here's my world gen and here is the config file if you need to see the values.

How do you know it stopped generating? Did you set a breakpoint? And when repeating a test, did you delete your nether files (or start a new world) so the chunks had to be generated again?
