Cells are of the form *Rate (X%)* where:

*Rate*
- (for crashes) is the number of that type of crash divided by the kusage_hours
- (for kusage_hours) is just the number of kusage_hours
*(X%)*
- (for crashes) is the percent that this week's number (not the rate) of crashes is vs. last week's number (not rate) of that crash
- (for kusage_hours) is the percent that this week's number is of last week's kusage_hours
Since crash rates are *#crashes / kusage_hours* a low *(X%)* in *kusage_hours* can result in an inflation of crash rates.

To estimate how much of an inflation, take a relatively-stable crash type (like *P*) and compare its *(X%)* to *kusage_hours*'.

As of yet, no model has been developed to do this properly, so YMMV.
