Float, the difference between Early and Late Dates is at the core of CPM scheduling. Baseline Schedule activities as well as any CPM Schedule activities do have Early Start/Finish Dates as well as Late Start/Finish Dates. I suggest showing Current Schedule as well Baseline Schedules Early and Late Bars.
The green/red bar represents Current Schedule Early Bar.
The white box represents Current Schedule Late Bar.
The yellow bar represents Baseline Early Bar.
The grey bar represents Baseline Late Bar.
Once you setup your schedule to display Baseline Late and Early bars you will not need to create any progress updates of your baseline, easy and gives you more information.
Using only Early Dates to compare planned % complete is wrong unless all activities are critical.

all of this is simply a math function of time
Scheduled duration % complete
start date = 1/1/2017
contractual time 1025 calendar days
finish date = start date plus contractual time
1/1/2017 + 1025 days = 10/23/2019 finish date
lets says the data date = 7/1/2018
days expended todate is data date - start date = 7/1/2018 - 1/1/2017 = day # 546
scheduled duration % complete = current data datae (or day number) divided by over all duration which is 546/1025 = 53.27%
actual duration % complete
from your updated schedule the new forecasted completion date = 11/23/2019
new time or new overall extened time is forecasted completion date minus the start date 11/23/2019-1/1/2017 = 1056 days
Actual duration % complete = current data dtae (or day number) divided by updated forecasted over all duration which is 546/1056 = 51.70%
