Misleading value for "Percent in the Market"

When I run a backtest in either MultiCharts or the Portfolio Backtester applications, the value for "Percent in the Market" is somewhat misleading or confusing. 
If I understand this correctly, it's reporting the time during which I had any positions in the market. For example, if I have a position in the market for sixty days out of a one-hundred day period, it will show "60%" as the time in the market.
The problem is that this doesn't reflect the percent of capital that is committed in the market. For example, if I have a portfolio with a value of $100,000, but only a $5,000 position in the market on a particular day, the programs will count that day as a "time in the market" day, even though 95% of the portfolio value is not being used and is sitting idle.
This is particularly a problem in the portfiolio backtester. I might have a strategy with a $100,000 portfolio, and strategies that make purchases of $10,000 per symbol. I have no way of knowing whether whether, on average, I'm using $20,000 or $80,000 of that capital on a given day. In either case, it wiill be reported as a "time in the market" day.
I would be good to have another value, like "Percent Commited Capital Per Day," that would reflect the actual available funds that are being invested per day. Thanks.
