Thank you! I think it's a very good method and very easy to apply. Basically most of the times I unconsciously do very similar to you. My reference is FCOM with the minimum altitude to be fully configured (1500/5NM on a 3 deg glideslope).
If I intercept the Glide in Flap1, I use my speed to set F2 at a suitable point, usually if my speed is 190 at 9NM but not latest than 8NM, then the gear and F3 (and Full if used) accordingly...
Thanks for your detailed reply! All the best
