140推薦信內容請教 - 移民

各位大家好
目前我正在跟律師一起辦NIW 現在還在準備140所有資料的階段
律師建議我準備四封推薦信 我也找到了四個獨立的推薦人
前三位推薦人基本上就是在律師擬好的信上簽名
所以律師看了之後都說沒問題
問題在於第四位推薦者 他在介紹他自己的領域時放進他自己的語言

My research focuses on the electrical, thermal, optical and
mechanical properties of graphene and other two-dimensional
materials. Graphene is a single layer of graphite, and has
been dubbed the “wonder material” – it conducts electricity
better than copper, conducts heat better than diamond, is
transparent like plastic, is more elastic than Saran wrap, yet
stronger than steel. Since its experimental isolation in 2004,
it has quickly emerged as the hottest system for condensed matter
physics as well as a potential post-silicon electronic material.
The 2010 Nobel Prize in Physics was awarded to Andre Geim and
Kostya Novoselov for their “ground breaking experiments”
on graphene. Currently major companies such as Samsung and Intel
are investing in graphene-based electronics. This is an immensely
competitive field, attracting some of the best and brightest minds
in physics.

律師認為這個potential是比較猜測意味 建議我請推薦者修改這字
想請問專家們 真的有必要因為這一個字 而讓整個package變弱嗎？
還有一點是 有時這些問題其實都不是律師親自回答 我有點猜測助理
是按照一些SOP來跟客戶回應

我也寫信給推薦者請他修正 但也久久沒收到回應 律師是建議找新的
但我不覺得有這必要（律師先前有說他們也可以用目前這封信進行）
請各位給個意見
