help me read this horary chart to find my ring

Friends ,

I lost my ring sometime in past 2 days ( Not very sure of it ) , I noticed it only yesterday . I browsed through and found that horary chart can help find the location . I am suspecting I lost it in my house or in office .

I am attaching the horary chart generated based on the inputs .

Could some one please help read the chart and let me know what is the input it is giving me regarding the location

Thanks
Siva M
