Not really. It still safe for your records with a 0.7 mil stylus. Up to 4 grams is safe, some sources would say 5 grams too.
As for the "don't play a side more than once a day", that was probably true for a mediocre tracking cartridge. Loescher (of Lenco) did tests and got away with at least 1000 (ONE THOUSAND) sequential
plays on the same record with no significant loss of quality using a good Shure cartridge of the late 60s. He claimed more than 2000 (TWO thousand) plays under the same conditions if using his wet playback fluid (which would leave a residue on the groove btw...)
This was an AES paper with photomicrographs and everything.
