Megalodon Spawning

So I've spent an embarrassing amount of hours hunting the shrouded ghost ever since it was released in shrouded spoils and I can't help but wonder sometimes about the actual mechanics of how megalodons spawn in general. What we know according to the sea of thieves wiki is as follows: they spawn randomly in open water, they'll spawn to attack you if you're idle for too long, they have a higher chance to appear if you have loot on board, and the deeper the water, the better. During my time shark hunting, I've used several different methods which include sailing island to island in deep open areas, sailing a loop around the entire perimeter of the old world in a square, and finding one spot to sit and wait. I've seen the most results with the latter. I'll sit and wait in a deep, wide open corner of the map, far from any islands or rocks, and store up loot from killing encounters. Then I'll stay idle for as long as it takes until something appears. Here are my findings: it appears, at least through the time I've spent doing this, that the quality and/or quantity of loot aboard does affect the likelihood of an encounter. When an encounter does appear, another is much more likely to appear either during or quickly afterwards. And lastly, the majority of the encounters have been crested queens. Now, who knows if these are actually representative of any real statistics or if it's simply how the dice rolls, but it's what I've recorded thus far. The encounter string I do believe has some mechanical truth to it however, because nearly everytime I've gotten and encounter, another follows immediately after, and sometimes another after that. The crested queens, I'm not sure. According to the sea of thieves wiki, any shark can appear anywhere, but I'm recording more crested queens than hungering ones even and they're a lower rarity (these encounters have largely been recorded in B20 on the map, at the bottom left hand corner). I started to question if the megalodons didn't have preferred regions for spawning but I haven't found any evidence of that and the wiki itself, as I said, denies it. If anyone has any input on your own experiences and possible theories of these mechanics, I'd be glad to hear them. At the time of writing this, I'm sitting in my shark hunting spot waiting for more encounters and I've already clocked in 6 more hours today for this hunt.
