Anti skating on Michell Tecnodec - Yes No Maybe ?

My Tecnodec has an oem version of the Rega rb250, modified with a Michell tecnoweight and VTA adjustment.

i just reset the VTF, and now I am playing with anti skating.  The dealer told me that he does not use anti skating at all, so it has been set to zero since he mounted the Lyra Delos on the arm 2 years ago.  Now that I am trying to learn the art of cartridge mounting, I am adjusting his handiwork.  I just set the VTF to the exact spec Lyra suggests, and now I am considering anti skating.

the Suggestion is to set the anti skate force to the same as the vtf.  I did this, but the control is not a very accurate / precise device on the arm I have.

how can I see if I have too much anti skate?  When I lower the arm to the record, the arm wants to slide a touch back towards the edge, making it slightly challenging to drop the needle on the record leader without it wanting to slide off!  Is this too much anti skate?  Should I drop it to 1g rather than 1.75?
