Other listed property.
(3) Other listed property. In the case of other listed property, the taxpayer shall allocate the use of that property on the basis of the most appropriate unit of time the property is actually used (rather than merely being available for use). For example, the percentage of use of a computer in a trade or business for a taxable year is determined by dividing the number of hours the computer is used for business purposes during the year by the total number of hours the computer is used for any purpose during the year.
