Resource Requirements Forecast (RRF) Object Reference
This RRF object is a collection of time-series forecasts of required pool resources and related statistics.
Time-series
A time-series forecast represents a sequence of intervals, where the start-time is the closed interval (inclusive) and the end-time is the open interval (exclusive).
Intervals may vary in duration. Values that rely on calculated averages are time-weighted to account for different durations.

PerfCaptureRate - numeric

Why hardware freshness matters
Operating hardware too long incurs both technology currency and financial costs.
Unnecessary costs are incurred when hardware life is extended too long relative to the cost of other resources in a pool, or when other resources in a pool are over-procured with respect to the arrival of more efficient or performant hardware.
Both diminish the opportunity to monetize the value of more efficient or performant hardware.

Asymmetric Inventory Turnover

PerfCaptureRate - numeric
Measures capture rate of performance within inventory turnover, and is calculated: weighted-average perf rating of server inventory divided by current perf rating in ServerPerf property in NewServerConfiguration object. The latter is treated as the current "market rate" for new servers.
Technology Currency
Perf Capture Rate is an alternative measure to chronological age that better evaluates the economic "carry risk" of hardware inventory related to:
- Rapid decay of pool hardware value with the arrival of better hardware.
- Highly perishable nature of hardware; today's low utilization cannot be recaptured tomorrow.
