No one is handing away anything close to 30 watts like that. They wouldn't hand away 5 watts like that.
0.215-0.195 is not 0.0015. It's 0.02 or about 13x the amount. You're miscalculating by a decimal place. If your CdA of .195 is taking 275 Watts and you add 0.0015 - that's 0.1965 and 277 Watts or 3 (not 30) extra Watts. Using your numbers,
