{{out|If the cunsumption consumption level of any resource can be easily upper estimated with some value, and this setimation estimation is lower than the limit, then we do not need to know the exact consumption level and allow the resource allocation without additional checks}}Apparently, when the estimation exceeds the limit, we must switch to the slower mode, that will give us more presice precise value of the consumption level and (probably) allocate another portion of the resource.
