Help with Ravencoin mining.

Hey, I'm new to cryptomining. I have picked Ravencoin after some research.

I need some help to get started.

I have 4Gb GTX 1650, Is Ravencoin the right choice?

I am using gminer, is that the best choice for Nvidia 1650?

I am mining on Beepool, is that good? (effort-reward ratio)

How many shares do I need to mine (it says share accepted), to get my first payout.

My mining rate is 6.85 is that good?

I receive 3 shares in 10 minutes, what does that mean? (I mined 20 shares 2 times yesterday, don't they count as 40 shares or my progress was wiped clean)
