Do pro players manage to consistently maintain high CS in early game?

As an ADC, I made a goal of getting 70 CS at the 10 minute mark. I can achieve this only in games where I have a very passive farming lane (rarely). Most of the time, there is a lot of harassing and some kills (normal games, I am Silver), and I get a lot lower CS then.

My question is: do pro players manage to keep their high CS score early game (around 10m) in a very aggressive lane? To rephrase it: whatever the CS they can achieve on a passive lane, does that drop much on an aggressive lane, or do they manage to keep the same CS score?

Edit: the reason I want to know this is to know whether or not I must be concern of the drop in my CS on aggressive lanes (I know 70 CS is actually low, I will set it higher when I achieve it).

Competitive players do not drop CS, generally.

On offense, a competitive player will time his aggressive pushes with two things in mind. Firstly, he doesn't want to miss out on his own CS. That is the most important thing. Secondly, he wants to try to push his opponent out of lane when his opponent should be taking his CS, so that the opponent misses creeps.

On defense, a competitive player will be trying to make sure they're in as safe a position as possible when the creep wave is coming, so that they don't miss out on CS.

The combination of these things does tend to make for lanes where both sides are essentially freefarming each other for long stretches, with occasional bursts of intense action.

Professional mid laners and ADCs tend to average around 100 CS per 10 minutes, while top laners will get slightly less possibly due to roaming or due to the nature of their champion not being well-equipped to take every creep.
