annotations - include the word 'sample' in the materials annotations?

[lfoppiano]

I'm revising training data generated using the anomaly detection script: #181
I have a question about some annotations.
Should we include the word sample in a sentence as follows:

The resistive transitions in fields between 0 and 7.5 kOe measured in field-cooling are shown in Fig. 2. <rs type="tc">T c</rs> of the <rs type="material">Nb/AAO sample</rs> is <rs type="tcValue">6.85 K</rs> whereas for the <rs type="material">reference sample</rs> it is <rs type="tcValue">7.5 K</rs>.

Currently, in SuperMat:

• 15 times is included
• 107+ times is not included

We might need to revise the existing data after taking this decision.
