     When you type in the name OTV 2 in the search box, that brings up a page with the general orbital elements of the satellite. This gives the perigee as 328.9 km. But then there is a link on the page near the top: "Track it now!"
     This gives the real time position and altitude of the satellite. As you watch it, over the 90 minute orbit it frequently dips down to around 296 km. But I'll email the maintainer of the site to see where these real time numbers are coming from.

    I accessed it using two common browsers, and I still cannot find any reference on that site to 296 km perigee for object
    11010A / 37375. Is it on some sort of altitude history plot? If the design of the site enables, I would appreciate a
    link to the exact page with the information you referenced. Better still, you should ask Chip to explain how he arrived
    at the value you claim to have seen, and then report back.
