Clearing up value adjustments

Does the earnings growth of the country (re https://www.serenitystocks.com/blog/adjusting-benjamin-grahams-price-calculations-today AND https://www.serenitystocks.com/blog/value-investing-across-countries-and-economies) affect the intrinsic value so it drops to around the 60% level for defensive and enterprising UK stocks (70% for US)?
So would it be correct to say intrinsic price for BWY.L is 44.42 GBP, so it needs to be multiplied by 140% before it reaches up-to-date levels, and the IV% to correct itself by 40% (144.6% to 184.6%)?
It looks fairly easy to understand, but I just wanted to make sure because increasing a stock's worth by almost half is quite a lot if it's interpreted incorrectly.

Does this also mean that UK stocks available on the Classic Graham Screener between 70-60% do class as "buys" after adjustment? TATE.L IV% - 65.97 would become 105.97%, for instance.

Thank you.

Dear Jeff,

Thank you for your forum post!

Graham's framework does need to be adjusted for prevailing interest rates, as well as for local inflation rates. So, most of your assertions above do appear to be correct in theory; but there may be slight differences in the exact numbers.

So, for example, the Intrinsic Value of a U.K. stock would need to be multiplied by 167% (100% รท 60%) for correction, and not 140%.

"Does this also mean that UK stocks available on the Classic Graham Screener between 70-60% do class as "buys" after adjustment?"

Technically, any Defensive or Enterprising grade U.K stock with an Intrinsic Value(%) above 60% would be deemed to have cleared the framework based on the interest rates and inflation rates given in the above links. That would naturally include stocks such as Tate & Lyle PLC (TATE.L) and Bellway PLC (BWY.L).
