Risk Rating_Number of KRIi calculations

Number of KRIi calculations is a number of slots in the sliding window of EscalationProbingDays (usually 60 days) counnting back starting from the current day.

For example data processing and KRIs calculation happened 1st time (its 1st data import), but value in denominator is not 1, it is equal to EscalationProbingDays. Here is how this number is calc-d:

samples are collected from window of EscalationProbingDays with frequency KriCalculationPeriodDays.

For EscalationProbingDays=60 and KriCalculationPeriodDays=1 it's 60 samples.

Then if there are more samples than MaximumKriSamples, the latest MaximumKriSamples are selected. If MaximumKriSamples=30, it's 30 samples.

NOTE: If several found with the same distance, use the last for that day.

The purpose of it that is that we don't want to escalate immediately on first data, we want to collect some data to check whether this escalation is not a random spike and have escalations based on big enough quantity of data.

After 30 KRI calculations the system will switch to 30 point in denominator and will not provide any head start. Which means if the KRI is still in high escalation zone or were in high escalation zone most of the time (most of 30 points were in high escalation zone), the risk rating will be escalated in 31st calulation.

Its possible to set EscalationProbingDays to lesser number in tech config. and have high site risk score on 1st import.

NOTE: If KRI calculation was disabled for some time and then was enabled again system will not treat it as a new KRI and will take MaximumKriSamples parameter into acoount for Risk Rating calculations.

All mantioned parameters EscalationProbingDays, MaximumKriSamples, KriCalculationPeriodDays can be setup in Technical Config.
