Bambu PETG-CF, low HDT compared to Prusament

I was going to order a spool of Bambu’s PETG-CF, but noticed the rather low HDT compared to Prusament:

Bambu HDT, 0.45 MPa: 74 °C
Prusament HDT, 0.45 MPa: 96 °C

Is this an error in the data sheet or is the HDT really that much lower?

Has anyone used both and can offer some impressions?
