Hello, guys
I started using the computer generated scrambles tow month ago. I am not struggling withthe finger tricks but the regrips. Can anyone give me some tips?

Just… do the regrips? Being able to double-flick (both index-middle and ring-pinky, with both of your hands, in any grip) and do other non-obvious fingertricks will significantly reduce the number of regrips you have to do, but you can't really avoid regrips entirely.

How long does doing a scramble take you on average?

Don't use this. It solves the wrong problem, and it seems to bias towards easy scrambles.
It's a really cool idea, though! Someone should build a proper one of these (assuming this one is not) which generates genuine random-state scrambles, and then we should switch to using it for official competitions! Could shave some seconds off of the time required to do an official round.

But in order to make a regripless scramble that is still random and equiprobable for each state, the scrambles would probably have to be longer, so it probably would save much, if any, time. I could be wrong about that though :)

I thought about this for a couple of minutes when I first saw the post on r/cubers, worked out how to write a regripless random-state scrambler (basically, do something like Roux FB or EOLOL, then solve the rest), decided it was too much effort and just went back to doing nothing important. It'll probably run into the exact problem ProStar mentioned: if you use a two-phase algo of some sort, the scramble sequences will be longer than our current ones, which cancels out the time saved from not having to do regrips. (If you want to do one-phase, i.e. optimal solves, then good luck waiting for your scrambles to even be generated…)

If you want to improve scrambling speed with "less" effort, using QTM-optimised scrambles would be an immediate win. I once timed myself comparing lots of random-state scrambles generated with Cube Explorer QTM and with min2phase; Cube Explorer QTM was a bit faster on average. (Another wild idea would be to use Alg Explorer to optimise the execution of a scramble by using wide/slice moves, but this probably helps less than optimising for QTM.)

Chris Tran did some work on making scrambles faster:

Seems that it didn't work out the way he had hoped though.

This made me think of a silly idea. What if we wrote a scrambler that deliberately make scrambles awkward to fingertrick, so that you get to improve your fingertricks whenever you scramble your cube?

I don't think it could work, but I found the idea amusing.

It definitely gets better over time. I used cstimer since i started in july 2019. Its just something you need to practice al lot. You can use this as training to practice difficult fingertricks as well.

Learn all the fingertricks you can.
I never actually tried to get better in scrambling, but as I learned new fingertricks with both hands I got faster and faster.

Here is a video of me scambling, notice the few regrips and various types of fingertricks with both hands
