i would not not focus on speed ,
i would focus on quality handling , judging a corner few meters before what you plan to do.
steering in advance as you built up on speed because you anticipate the skid.
sad to hear about crash but learn from it what went wrong ., without mistakes you cannot learn ,, anyone who ended in crash needs to go back to previous handling lesson. jumping ahead ends in crash.
you anticipate will happen make sure there is space to correct the mistake before crash happens.
thats why videos are impt for replay,,
