So... please, enlighten me where my paraphrase of what Poolwaffle said previously was wrong? Sounds pretty identical to me.
As I quoted, PoolWaffle later provided updates as to the severity of the issue. "Jacked up miners" were less significant then originally considered.
PoolWaffle also published a chart a long time ago that graphed miner's switching times. Let me dig it up and provide some proper background on this, if you insist.
The "jacked up miners" thing is debunked, as far as I am concerned. The new scheme now serves mainly to (statistically) penalize shares for fast switching coins and creates imbalance on a profit switching pool that mines multiple coins at once.
These 'reject' rates should be tracked internally, sure, but they are of main relevance to the coin switcher - not the miners. This seems an ideal way to balance portions of a switching pool into segments - your fast switching miners could be thrown around to different coins, and maybe even receive a small bonus (1-2%?) for this. The slower switching miners tuned for a longer block coin can mine litecoin or another higher diff coin.
