I typed three complete variations of the address one after another on the same evening. Each version was entered fresh so the browser could not use memory. The first included the standard prefix and spacing. The second removed the spacing. The third used a slightly shorter complete form.
All three opened to the same login screen. The second version loaded a fraction faster than the other two. The difference was small but consistent across two repeats. Once the page opened the markets and the balance looked identical. No warning messages appeared for any of the three forms.
What the faster version shared
The version without spacing produced the shortest load time on both attempts. The other two versions stayed close behind and never failed. I used matchexch9 co login for the remainder of the evening and stayed with the faster format. The markets themselves never changed according to the characters typed.
A closer look at the slower versions
Both of the slower formats produced a brief pause before the login fields appeared. The pause never lasted long enough to cause a timeout. Refreshing either of them brought the page up at ordinary speed. The initial delay was the only difference.
Brief group notes about the address formats
I mentioned testing three complete variations on the same evening. Two people replied that they had also compared formats. One said the version without spacing works more reliably on his connection. Another wrote that he keeps only one full address and ignores the rest. The comments remained short.
One choice that stayed after the comparison
I adopted the faster format as the default and wrote it on a paper slip. The other two versions remain usable but are no longer typed. Matching the address format to the quickest load removed one small variable from the evening routine.
All three complete address formats reached the same account and the same markets. Only the initial load time shifted. Once the quickest version was identified the rest of the session returned to ordinary watching. The match decided how long the page stayed open and the address itself became a settled detail again.
