I'm familiarizing myself with RE's backtesting (simulation) features, and I wonder if someone can help me understand the "System Results"?
First off, here's the "Position List" within the "System Results" tab:

I'm looking first at the bottom pane of the above screenshot (let's call it the "detail pane"), where it breaks the position into the two trades that comprise it. (The same info is also shown in the "Trade List" tab.) Each trade is either a buy or a sell of a single contract of PA futures, with a commission of $2.50 per side. My PA futures symbol has the following settings:

So, I understand where most of these values are coming from, but there are a few that I don't. I exported the two trades in the detail pane to CSV and opened them in Excel:

I see how the value in cell G2 is calcuated: It debits my account capital by the Initial Margin plus the per-side commission, or -($5000.00 + 2.50) = -$5002.50. I also see how the profit is computed (contract size * difference in buy and sell prices - round-turn commission). These make sense.
My questions are:1) What does $4779.33 in spreadsheet cell G3 represent? What is the formula for computing it?
2) This simulation was based on 5 minute bars. Why do the fills show times that aren't a multiple of 5 minutes?
A: I answered this one myself... have a look at the bar data editor screenshot below. There is very sparse data, so I assume RE uses the next available bar after the signal is triggered to generate the fill.
3) This symbol has a minimum fluctuation (tick size) of 0.05. Why are the fill prices not multiples of 0.05? (Note that this is 1 contract, so there is not an average fill price at work here.) I checked the bar data editor just to be sure, and all the prices there are divisible by 0.05:

Thanks in advance for any help you can provide
