Were you experiencing unnecessary volatility as a result? A two dollar change just because bidask widened out in a single stock are a lot of vegas
Just stating how my positions have always been marked.

what does this mean?
... I had to laugh at that.... 
IF you require accurate near real-time PnL tracking, you may want to investigate other tools to address that (that don't pull the rug out from under you). (Assuming your broker does not address this quickly). OptionNetExplorer, was good the last time I used it. You may also create your own (but amount of development effort is likely not worth your time)This morning (at 10:30) my pnl was down 30,000. Of that, 20,000 was dumb marks meaning I'm really down 10,000. Right now my pnl is -5,000 and bad marks are -10,000 and +15,000 meaning, I'm really down 10,000. This makes sense but I have to spend more time verifying that something in my single stock basket isn't blowing up. It creates a poor allocation of my time and mental energy.
I am surprised more people aren't bothered by this concept of marking to mid vs the algo that was used before.
