> I tried VBILX, for YTD old M* chart was close at 9.05, new chart 8.77%, real number 9.06 Real number? According to whom? Morningstar? That's a secondary source.
>Chuck says VBILV 9.04 YTD I say I can live with .04, .05, or .06 !
Consider chucking Chuck. That's a tertiary source: "Except as noted below, all data provided by Morningstar, Inc." (Footnote on Chuck's page for VBILX)
Of course Vanguard is correct. You can prove it yourself.
Start with 100 shares purchased on 12/31/2019. Calculate the dollar amount of the divs paid each month and how many shares that buys based on the end of month reinvestment price. (Vanguard provides a table with all this data here.) Add those shares, rinse and repeat. After 11 months (divs for Jan-Nov), you'll have 102.107 shares.
Add to the current (12/4/20) value of those shares the accrued divs for four days. One can approximate that by taking: 4/30 x Nov div/share x 102.107 shares = 28¢
The increase in value (from $1181.00 to $1287.85) , is 9.05% of the original value.
Does M* calculate fund metrics (for example risk and volatility measures or value and growth measures) themselves or is data provided by a third party?

M* site shows you several risk metrics see (this) or the old site was easier where you can compare several funds see (this) PV is a great site with many metric and you can run different scenarios and trading dates, see (this)
For some calculations, it relies upon the first party, i.e. numbers are calculated by the funds themselves. For example,
Morningstar asks fund companies to calculate and send average effective duration (also known as “option-adjusted duration”) for each of their fixed-income or allocation funds.
Morningstar Fixed-Income Style Box Methodology, p. 4
As to third parties, it relies upon NRSROs for bond ratings (which the funds roll up into histograms of their portfolios). M* then uses this data and its own formulae to calculate average credit rating for a fund.
It uses third party estimates of projected EPS for stock, though "When a third party estimate ... is not available, Morningstar calculates a projection ... based on historical growth rates up through the most recent year". This in turn is used in evaluating where on the value/growth spectrum a stock, and ultimately a fund, sits. Morningstar Style Box Methodology, p.8

BTW, the new chart shows 9.0584% from 12/31/19 to 12/4/20. Take a closer look.

Likewise, it gets SEC yields from the funds themselves.
