Actually you are right I applied CS to the wrong era. Which means on pure economy beakers HS lost half the value of CS over the 10 turns. Losing 1352 beaker the next 10 turns. Excluding bulbs and free techs HS were down 3-4k in techs over 30 turns. Which was likely due to PR science even at 0% around T95 almost matching HS science at 100%. As LTC said grabbing great people much sooner really helped our game. Allowing the double bulb of astronomy and philosophy.
