A high MPI can hide a falling RGI.
A hotel can post a Market Penetration Index well above 100 — capturing more than its fair share of occupancy — and still be losing, because it's winning those rooms with business priced below what the market will bear. ARI slides below 100 even as MPI climbs. And because RGI is just MPI and ARI combined, the revenue index erodes while the house looks full.
MPI (occupancy index) above 100, rising. ARI (rate index) below 100, falling. RGI — the two combined — eroding. MPI up plus ARI down means filling rooms and pricing them too low.
MPI up. ARI down. RGI eroding. That's the fingerprint.
One index pattern exposes wrong-business displacement, and it reads straight off the STAR report an asset manager already gets every month: a high or rising MPI paired with a falling ARI, dragging RGI below 100 and trending down across quarters. Read in isolation, each looks survivable — MPI above 100 looks like strength. But MPI above 100 with ARI below 100 means the hotel is capturing more than its share of rooms by giving up rate, filling the house with business the market values less than its competitors'. What matters is not a single month but the rolling trend: a one-month ARI dip is noise; ARI below 100 and declining for three or four quarters while MPI holds is a property losing its rate position to its comp set — systematically, and for a reason buried in the booked mix.
From a falling ARI to the accounts dragging it down.
Each step is something Aria does against the systems you already run — reading them, never changing them — to turn an index symptom into a named cause.
It tells you ARI is below 100 and RGI is eroding — it can't tell you why, because STR only sees blended performance against the comp set, never your booked mix. That blind spot is exactly where Aria begins.
By segment, by channel, by day-of-week, across years. The erosion isn't broad — it's concentrated. Transient share, the rate-rich business, gives way to contract and volume business booked at rates that pull blended ADR, and ARI, down.
The negotiated contracts that have quietly grown into the property's compression nights — holding rooms at rates set for a softer market that no longer exists. They keep MPI high and ARI low.
On the highest-demand nights, ask what the property turned away — and find the higher-rate transient and group business that was declined because the rooms were already committed to low-ARI contracts.
“Your RGI is down because a specific set of contracts is winning you occupancy you don't need at rates that are sinking your ARI — and here is exactly the higher-rate business you turned away to honor them. The STAR report shows RGI at 94 and falling; here is the account behind it.”
The STAR report is the symptom. The mix is the disease.
The monthly report tells everyone RGI is eroding. By design, it can't explain why — STR benchmarks your outcome against the comp set, not your composition. Diagnosing the cause means joining booked mix, contracts, and denied business to the index trend, across a horizon longer than any operator's tenure. Three forces keep it hidden in plain sight.
Time, incentive, and timing all work against seeing it.
RGI erosion from mix drift accrues over years. Operators run the quarter in front of them and turn over; the memory of when ARI was still above 100 walks out with them.
A high MPI looks like winning. Occupancy is up, sales goals were met, the accounts are relationships. Nothing rewards asking “should we have protected those compression nights for higher-ARI demand?”
This isn't a rate the revenue system got wrong — it's a commitment made before pricing happened. By the time the low-ARI rooms are sold, the trade is already locked in.
The evidence to lift ARI — handed to the person who can act.
Aria assembles the case in the owner's language: the multi-quarter MPI / ARI / RGI trend, the segment-level ADR decomposition behind the ARI slide, the specific accounts driving it, and the quantified value of the higher-rate business displaced. Then it routes to the decision, scaled to the lever the owner holds — flag the specific contracts whose rates no longer fit the market for renegotiation at renewal; recommend how much compression-period inventory to protect for higher-ARI demand; and assemble the multi-quarter index story for the conversation about why RGI has been below 100, and what mix gets it back above.
Aria never cancels a contract or sets a rate. It surfaces the trade, quantifies it in RGI and dollars, and hands the owner the evidence. The operator still runs commercial strategy — now with someone watching the index trend on the owner's behalf.
