It was found that the data from 1850-1937 show a decrease in the suns diameter a tenth as great as that which Akridge quotes. He has used the time honoured Creationist method of using EXTREME partiality by presenting the WORST case as FACT & then extrapolating everything from these figures. The two men whose data he quotes out of context are Eddy & Boornazian. I quote from a 1979 report In Science News.
"The shrinkage does not apply to the entire solar mass, but rather to the suns outer layers. Since the rate of shrinkage is so fast, the two researchers believe is is only a temporary contraction phase. "Its unrealistic to assume this will continue" Eddy told Science News. " It does seem to imply the Sun is oscillating in some way""
Also, Scientists of the University College London & Royal Greenwich Observatory calculated from transits of Mercury over the last 3 centuries that there was evidence of diameter oscillation with a period of about 80 years & amplitude of .025%.
Subsequent studies support this theory, giving a period of 76 years.
