Jim,
Attached are the F-Class rules. 22.3.4.1(b)(2) is quoted below.
QUOTE
(2) The use of any form of a table is prohibited. Separate flat boards or plates not exceeding the dimensions of the individual rests by two inches are allowed to be placed under the front and/or rear rests. In the case of a bipod, the board or plate may not exceed the width of the bipod by 2", nor be more than 12" front to rear. See Rule 3.4.1(a)(1).
No leveling screws or protrusions are allowed on these boards or plates. They must be flat on the top and bottom.
This discipline is a modification of high power prone shooting, not a form of bench rest and should not be construed as such.
Disabled competitors may apply to the NRA Protest Committee for appropriate dispensation.
The intent of this rule is to prevent the use of a table type device.

So doesn't the complete top surface need to be UHMW, as they are not , per the quoted Rules, "Flat on the bottom and top", the 2 rows of tape are similar to the "Rails" I've seen added to boards for the "skis" to slide in, which didn't make it past Tech.
"No leveling screws or protrusions are allowed on these boards or plates. They must be flat on the top and bottom."
Also don't think that the plate is legal for Open Class with your Rest, as it is limited by the "no more than 2" rule"
3.4.1 Rifle Rests -
(a) F-Class Open Rifle (F-O) - The rifle may be supported by any means which provide no positive
mechanical method for returning it to its precise point of aim for the prior shot. Subject to:
(1) No more than two rests may be used. If two rests are employed, they may not be attached to each
other.
(2) The use of any form of a table is prohibited. Separate flat boards or plates not exceeding the
dimensions of the individual rests by two inches are allowed to be placed under the front and/or rear rests. See Rule 3.4.1(a)(1).
I use a Harris, Pod Lock with Pod Paws on a 1 1/2" x 10" x 8" bare naked steel plate with a handle to carry it.
Or a Laberge on a plywood plate that's 7/8" x 27" x 12" for both F/TR & Open and even sometimes a Caldwell Rock BR which has a set of Super Feet and sits on the ground.
