The RSA shows up to 3 headlines, while the ETA shows only two headlines. Similarly, the number of descriptions shown varies in both cases; for example, for RSA, up to 2 descriptions (each of 90 characters) are displayed, whereas, for ETA, only one description of 80 characters is displayed. In the end, a critical difference is the total max length which is 300 for RSA and 150 for ETA.
