Calculate average velocity from previous 3 sprints

Hello all,

I'm trying to calculate the average velocity from the previous 3 sprints, so I can then calculate the variance of the current sprint velocity against the average velocity from the prior three sprints.

Here's a trimmed down view of the data I'm working with:

Sprint nameComplete dateSprint Velocity
ENRL | FY24 Q2 SP0911/29/202339
ADM | FY24 Q2 SP0911/29/202317
AAAMT | FY24 Q2 SP0911/29/202334
ENRL | FY24 Q2 SP1012/13/202346
ADM | FY24 Q2 SP1012/13/20238
AAAMT | FY24 Q2 SP1012/13/202313
ENRL | FY24 Q2 SP1112/27/202316
ADM | FY24 Q2 SP1112/27/202319
AAAMT | FY24 Q2 SP1112/27/202326
ADM | FY24 Q2 SP121/17/202427
ENRL | FY24 Q2 SP121/17/202413
AAAMT | FY24 Q2 SP121/17/20240


Here's the approach I've tried, but it's not producing the expected result:

Avg Velocity Past 3 Sprints =
CALCULATE(
    AVERAGE('Sprint Predictability Data'[Completed work]),
    FILTER(
        ALL('Sprint Predictability Data'),
        'Sprint Predictability Data'[Complete date] < MAX('Sprint Predictability Data'[Complete date]) &&
        'Sprint Predictability Data'[Complete date] >= MAX('Sprint Predictability Data'[Complete date]) -3
    )
)

Can any of you offer suggestions on how I might write this Dax measure?

Thank you!

@Benx So like this? PBIX is attached.

Better Rolling Average =
VAR __EndDate = MAX('Table'[DateIndex])
VAR __StartDate = __EndDate - 2
VAR __Table =
SUMMARIZE(
FILTER(ALL('Table'),[DateIndex]>=__StartDate && [DateIndex]<=__EndDate),
'Table'[DateIndex],
"__Value",SUM('Table'[Sprint Velocity])
)
RETURN
AVERAGEX(__Table,[__Value])

Thank you @Greg_Deckler ! Unfortunately, I'm having trouble making your solution work, as I'm not always dealing with a stadard period for the rolling avg. I want to dynamically capture the Sprint Velocity from the  prior three recorded dates. These may fall over the past 6 weeks, but not always. 

I created a DateIndex to assign a number to each distinct date, thinking this would give me what I needed to calcualte the rolling average, without using time intelligence functions. This also has not worked.
This is an example of what I'm trying to acheive.
