I'm answering a different question but are you even allowed to use window sprinklers in this case?
IBC 2012 703.4 Automatic sprinklers. Under the prescriptive fire resistance requirements of the International Building Code, the fire-resistance rating of a building element, component or assembly shall be established without the use of automatic sprinklers or any other fire suppression system being incorporated as part of the assembly tested in accordance with the fire exposure, procedures, and acceptance criteria specified in ASTM E 119 or UL 263. However, this section shall not prohibit or limit the duties and powers of the building official allowed by Sections 104.10 and 104.11. Generally speaking window sprinklers are out. But may be allowed by specific approval. To your question I've too only seen calculating one side. If you go back to the original test report one side is justified based on the testing parameters.
