..speed map checking for me happens towards the end of my review process for all my "systems" so this aspect not super critical
..1. check that likely pace & placement for my selection/s is positive
..2. also reconsider non-selections..in the market..& look suitably placed
..sometimes as a result of point 2..I have a saver or two
..at the moment I'm mainly using the free one provided by racenet
..am finding it generally reliable
..there's a few other freebie sites I'm yet to look at more closely & haven't touched on payed sites
..hope this helps
