I use to put a substantial amount of weight in subscription numbers. Not so much anymore. I tried to run forecasting models, and the input data is assumptions, therefore it provides skewed information.
Meaning, some are free, others single, others family plans. I was unable to truly get a baseline figure for each, the data fell somewhere between $2.50 and $25.00. Huge range, and useless from a statistics perspective.
I'm more leaning to $6.00 per each based on subjective variables. With revenues being substantial down the road, but not at this time.
Just my take.
